I hear you and of course the expectation would be that we would see something replace the talent - they are doing that all over the place in 5.4 as they scrap talents, redesign, move things baseline, etc. I was solely talking from a overall concept. I still can't understand why people think locks have good self heals - it's garbage compared to last couple xpacs. I'm perfectly happy training one all day because they have to spend health (tap for mana, trinket, etc) so the self healing has a balancer don't forget. Sure we'll give you their self healing, only BW now takes 20% of your health and you have to sac health to regen focus. =p
BTW, there's now a blue post that explains what I had assumed was the case: the damage reduction removals were for PVE. In PVP the affected classes should be getting compensated.
To those wondering why Aspect of the Iron Hawk was only reduced in damage reduction rather than removed, this is because it's a talent and it still needs to have a purpose.
