There are many advantages to open tapping, but also disadvantage. Obviously, with the way mounted combat was designed open tapping was needed in the rohan zones. I often leveled/quested with 20 mounted orcs in tow (or some rediculous number) that I all picked up with aoe skills, and if it was not setup for open tapping that could be seen as "mob stealing" as I was training a whole field of orcs on my tail, and no one else with a kill-so-many-orcs quest would get one until I killed em all. So there is a need.
I do love open tapping in the older zones too. But I do agree to a POINT with the topic starter as it prevents people from being forced to group with each other. My example: when questing in Moria I needed to fight a 9k elite baddie. No big deal, I had soloed him before on other toons so I went to work to get to him and started the fight. I noticed a burglar in the area doing quests, and not long before I finished the mob all over sudden there is the burglar in front of me delivering the final blow. He had sneaked around me and the fighting mob, and could now easily get the quest mob with 1 jab.
I am guilty of the same of course, a good many times I arrived at a quest baddie, only to find him with 30% health left and being fought by another player. Of course then you join in for the kill. Even worse, I arrived at Bugud with him with only 15k health left and came in just for the final kill shot. And he was being duo'd by 2 people who had done all the work. Now of course in both cases no one lost anything, except maybe the annoyance that someone got the quest completion with very little work.
This all said, I think open tapping is good, but maybe it should need an adjustment. I'm fine with getting quest credit for a single hit (as in a "kill 10 orcs" kind of quest or kill the boss), but perhaps the experience gained should be changed: FULL exp for the engaging player, AND full exp if in fellowship for everyone, but only a QUARTER exp if you come in and just add 1 shot just so you get the exp.
Also, I think LOTRO should focus more on fellowship play. I have completely soloed my LM to level 85, give or take one or two fellowships, and although I think it should not be impossible to solo, perhaps an advantage should be added to fellowship play. Perhaps a 10% exp bonus on kills for every group member up till 6, provided everyone in the fellowship is in a 10 level radius. (You don't want to have 3 level 85s doing hytbolds anyways grouped up with a level 20 in barows, a level 52 in moria, and a level 70 in dunland just to get the exp bonus.....).
I also think there should be more/better/revamped low level content. Some of the original zones may need a Moria-like makeover. I love Moria the way it has become after the revamp and enjoy leveling there. I also think there should be some new instances based in the older zones that would entice group play a bit more.
