Ok, I know there are other threads on this however I am going to post my description of the problems with the Draigoch raid encounter here on the theory that unless this issue is in Turbine's face day after day they won't fix it properly. They've had bug reports out of the encounter since the day it was released and still the same problems occur with great frequency.
First of all. the Draigoch encounter is one of the premier end game experiences in LOTRO. It's a keystone for a lot of players who want to kill the dragon and want some of the loot that only Draigoch drops. This makes it a very high profile part of the overall game. When players see this bug out as often as it does it goes to the heart of LOTRO's image as a stable game that produces enjoyable experiences for it's player base.
Secondly, the bugs in Draigoch often produce player's first ventures into the in-game support systems. This is because other minor bugs in game play, which happen occasionally, don't cause players to try to get support from the in-game support personnel. The fact that there is *no* in-game support for this problem other than a form letter that tells players there is no in-game support is just a terrible way to introduce most players to what should be a valuable part of the platform for Turbine.
Because of both factors above the Draigoch encounter is essentially a self-inflicted wound by Turbine.
Ok, that out of the way, here is the Draigoch Bug Raid described to the best of my ability. The bugs do not occur every time and they tend not to occur in very tight groups that have set rules for what can and cannot be done during the encounter particularly in phase 3. There is one bug however that will take the encounter down every time, it's just an exceedingly rare occurrence.
Draigoch Bug #1 - The extra Fellowship Maneuvers after the 12 for the challenge are complete.
In order to complete the Draigoch Challenge the raid must complete 12 specific Fellowship Maneuvers in a set order. Once the 12 are done and Draigoch is killed the challenge is fulfilled and people reap the rewards.
Here's the bug: if at any time after the 12 maneuvers are completed a random Fellowship Maneuver ("So-and-so has broken Draigoch's defenses!") occurs while Draigoch is on the ground being DPS'd the odds are excellent that Draigoch will be bugged the next time he gets back to his feet. He'll be green and not target-able at that point and the raid is over.
It's not completely clear if somebody has to click into the Fellowship Maneuver in order to initiate the bug and the person who broke Draigoch's defense doesn't have the option to avoid that anyway since the color wheel automatically comes up for them.
This bug has cost my kin their last two runs at Draigoch when the dragon was under a million morale each run. It has periodically cost us other runs, although it does not happen every time. It has had a frequency of about a third of our runs since the Draigoch encounter was released. I also run with other groups that are smaller and tighter and the bug happens much less often in these runs but is still present now and then. My kin tends to want to show new people the fight and that is why our frequency is so high in my opinion.
Draigoch Bug #2 - Captains using Escape From Darkness while Draigoch is stomping around making people bounce.
This bug usually results in the person being resurrected coming back at the entry point to the raid encounter instead of the Captain who res'd them. They are locked out of the encounter and Draigoch targets them and becomes green and not target-able himself. The raid is over. The bug only seems to occur when Draigoch is doing the stomp around after he lands from the fire-breathing phase in phase 3.
This bug is more addressable by the raid and we have a standard policy now that Captains are not to use Escape From Darkness in phase 3 unless the raid will wipe otherwise.
Draigoch Bug #3 - The person who has aggro from Draigoch's head in phase 3 goes link dead.
This bug occurs only when the person, usually the tank, who had aggro from Draigoch's head in phase 3 goes link dead. Draigoch never resets his aggro at that point and goes green and not target-able and the raid is over. Note that if the tank dies and somebody else gets aggro there's no problem, it's only when the person with aggro goes LD that the raid is bugged and over.
Those are the 3 predominant bugs in the Draigoch fight. Between them they cause a bug rate that is so high for some kins that they just won't waste the time running what should be a keystone achievement for every top end raiding kin. The bugs destroy much of the social element in high-end raiding because they make people leery of players who have not seen the fight yet. Looking for an experienced tank, healer or DPS group leader is one thing but declining a newly 75 hunter or champion or burglar because of fear they will bug the fight out is quite another. It's no fun to have to restrict yourself to a safe dozen to run this encounter every time because any new player could well bug you out. Not wipe you - bug you out.
Now the secondary issue is the customer service on this. It is unacceptable for the response to the problem to be that there is no response to the problem. This is not a rare bug that takes a lot of analysis. It is an eminently reproducible bug that destroys thousands of hours of customer play time and experience. There should be a fast resolution to the problem that involves rewarding the players for accomplishing the task of defeating the dragon when in fact he would absolutely have been defeated if the bug did not occur.
If you get to phase 3 and have him under a million morale, when most of the bugs occur, he is toast unless the raid is already wiping. Having a customer service representative come in and count noses and look at Draigoch's health should be enough to award a kill and the end chests. This isn't a plea for charity here. It's a plea for common sense to rule the day. Draigoch is a farm animal at this point for almost everybody who is running him. I can recall one actual wipe in the encounter over the last three months. Every other failure was bug-induced. Turbine needs to fix their customer service on this issue and they need to fix it fast because the people that are having trouble getting Draigoch down are not doing so because they're bad players, they're having trouble because in this instance Turbine are bad coders.
The customer is right and especially so when the provider is momentarily and systemically incompetent. Fix this.
