Tank Stances and WHY???

[Hasrat]

Except in this case, the buff is literally only enmity generation. There's no extra health, no extra defense, no penalty to damage. Yes I generate extra enmity or no I don't - but I see your point.

To the player, this sounds simple. "Extra" or "no extra." But the game still has to run the numbers, and the snapshot buff may provide a different value/multiplier than what is applied while synced.

You may think it doesn't matter. But consider 8-mans. Consider an off-tank that may have this snapshot potentially-higher generation, with a main tank that simply cannot stay ahead.

Not saying this is definitely what's happening. But, never know when they're something under the hood running unseen.
