I appreciate your legacy. You created and maintained the first enhancement BiS thread. But you let someone else take over for you for the one after that. And now you're telling the people working on the current list they're idiots for not doing things the way you want them to. If you really wanted to be in charge, you could have done the work yourself. It's their game now, play (nicely!) by their rules.
We are now in new territory; a defensive cool down is a requirement for a max DPS thread but Ancestral Spirit (one of the largest DPS gain talents available to us under certain conditions) is optional. This is exactly why I said we should focus only on the data objective (finding max DPS according to enhsim) and leave the utility to asterisk marks and discussions.
On SR, Coch, I think it’s a crap talent because there is no boss ability that is designed to one shot me unless I make a mistake, so I never NEED 30% reduction of dmg taken. If I did, everyone would need it and every spec would have an ability like this. They don’t. Further, since I am able to instantly heal myself more often than not, I would rather use a heal from time to time than suffer what I believe to be a badly designed talent point permanently.
If you really want to get down to the math of it all, you would have to model the DPS gained on every encounter by ½ imp shields (or whatever) x the number of encounters over the life of your character, then measure that against the DPS done for every second after SR saves your life (and I mean exactly that- times where had you not used that talent, you would have certainly died). I have been using that talent since it was made available (in whatever variety) and I can tell you that is has not saved my life that many times. Sure it’s saved my healers some mana, but rarely has it saved my life since I generally do what I am supposed to do.
My job is to do dmg. My healers and I (enh are perfectly capable of healing to acceptable levels during all the mechanics you have listed) have healed me through many of the mechanics you have listed and bosses have died as a result (surprisingly, I expect more to die in future). Further, SR’s value reduces to almost nothing the more your farm gear/become more experienced during encounters. TLDR; you don’t need SR. Neither does this thread. If people want to take it, let them. If they don’t, don’t call them stupid.
