I pulled this over from the Stalwart Defender discussion:
Bear in mind, and LeLoric can correct me if I'm wrong. He's talking about the "NORMAL" quest requirement, which in the rest of his thread he states as being rather high at that level.
I'm not sure where LeLoric stands on the Wings issue, other than he'd rather not have Chains be spammed, but the above statement makes no mentioned of Leap of Faith or any of the other "Flight/Jump" abilities. He specifically states that the DoT/Shield Block method is easier, and should be checked somehow. It is not Leap of Faith that is the game-altering tactic that it seems to have been perceived to be.
This is a call to address Tanking and Tanking Classes and Prestige classes to make them viable not only in the new Raids but elsewhere. I personally still see tanking, but as I do not play one, I'm not aware of the challenges they're going through to stay "in the game" so to speak. One of the best I know is a Paladin/Rogue Evasion Tank, and even he admitted it was a carefully planned build.
Once again, the mention of DoTs in play. No mention of Wings, and no specific mention that these are divine DoTs, just casters in general. Again, LeLoric please correct me if I am misreading the results of the test. The mechanics of the Raid, and indeed, Defenders needs to be looked at. Even the DoTs should be under review, not simply a single ability that happens to make Kiting a bit easier, because there are other easier to acquire abilities that make it just as easy, as has been previously mentioned.
Mmmm Pie. But I digress...even here, there is compromise, but the idea of a Caster tanking just seems odd to me. As I said, perhaps I run with reasonable types that like a balanced party, I don't know. I have seen the DoT/Block that people are talking about, but honestly, not too terribly often. Favored Souls, whose damage output does not match Arcane DoTs, aside, there seems to be a flaw in the root-cause analysis here.
