Warden had a very unique way of keeping aggro from unlimited mobs = threat leeches. The only source of threat will come by the hand of DPSing, which means a lot of resists and attacks BPEd. We are going to have to tank like Guardians in ROR (they have had some awesome changes, by the way, all in the good direction to make them better tanks in AoE and ST), only we have way less resources for that: 0 forced taunts, 0 pure threat options, 0 ranged threat match-up - they will have a great range of all that.
If a group of mobs go to a DPSer, you will have two options:
-DPS with lifetaps on them from range (good luck with the light dmg not being resisted) which, resisted or not, will take some time to get them back.
-Run like a chicken to melee range (if you can, certain bosses wont allow you to) and throw a DC (if it's not on cd) hoping there are not more than 5 targets (on Beta 6 threat match-up only affected 5 random mobs around you) and run back to your position.
Our only threat match-up skill, DC, needs you to be very close to the target to be effective. And you better don't have more than 5 mobs around you otherwise it might not even work on the mobs you wanted to be effective. This is by far the most uncontrolled and limited AoE threat I've ever seen. Just the mobs spawning at BoD 1st boss are a nightmare to grab, and by the time you get to generate enough aggro on them the healer or squishy DPSer will probably be dead anyways.
There are these things that players in beta asked for a million times:
-longer buff durations
-get more threat match-up option other than DC, non damaging ranged AoE threat gambit (Resounding Challenge?) and ranged ST (Wages of Fear?).
If they increased a bit buff durations and implement, for example, threat match-up/increased threat to Resounding Challenge and Wages of Fear, I'd say the class would be back to life. Not finished at all - there's a lot of things that need to be polished, there are a lot of things wardens are missing like a decent Blue Capstone Trait and Skill that is just horrible - but hey, that would at least be the bare minimum to let the class go Live until the other changes come.
Regarding threat-leeches: another really important thing that they took away with threat leeches is our ability to tank unlimited number of mobs. Now we are limited to 10 targets (lifetaps), while other tanks are limited to 13, for example. Funny for a premium AoE tank. We have no control at all on more than 10 mobs, since we can't control who does our lifetaps affect.
I really hope to see some of the most important changes players asked for weeks in Beta are implemented on monday, otherwise I'll have to level up a Guardian if I want to play a tank.
