Update 6 has almost fixed the Warden. Almost. Right now (meaning just after Update 6 launched and before the first patch), we have a way to reliably get aggro quickly and hold it for a long times with periodic refreshes. This allows us to build and execute defensive and self-healing gambits to try and keep ourselves alive once we are getting pounded on by the mobs we have aggro'd. And these defensive and self-healing gambits have been adjusted so that they provide enough benefit to actually help us in a meaningful way. Sure, there are still some bugs (Shield Tactics still allowing me get stunned, dazed, etc), but it is a HUGE step forward.
If something is adjusted in a future patch to reduce our ability to quickly grab aggro, we will then need a MAJOR boost to our self-heals and our defensive gambits to compensate for the extra time we will have to put into getting threat. Hmmm... I wonder if anyone would complain about Conviction ticking at 800 a pop or Shield Mastery giving a +5000 to block, parry, and evade and raising the cap for Wardens on these stats? And the other defensive and healing gambits adjusted similarly?
And if any adjustments to threat are made so that we "only have to use 1 or 2 more" threat building gambits at the start of a fight to get aggro and refresh them "only a little more often" to keep it, guess what? We will be broken. As you read this post, please think about what I am saying in the context of full raid endgame content that you have done or attempted to do. When 2 Wardens realistically can serve as the only tanks in Saurman T2, we'll be in pretty good shape.
Final note: I think it was Sapience who said in another post that Battle Preparation has been allowing Wardens to go into battle a little too well prepared. Have I missed something? Has there been a huge increase in wardens successfully tanking endgame raids since the update? Has the update made Saurman T2 trivial when 2 wardens tank it?
It seems like some of the arguments in this forum are based on the analysis of one or 2 aspects of the warden class looked at in a laboratory. I know this post is long, but if we don't get this conversation grounded in reality, wardens will continue to be viewed as broken. And they will be.
