I'd say this makes glyph of deterrence the new baseline. Obviously not huge differences anymore, but that one is always nice to have. For me anyway, this pretty much means Glyph of Animal bond, Glyph of Deterrence + 1 whatever you feel like/may possibly help the specific fight. I'm still not quite sure how I feel about liberation, we'll see how it works out with the new fights, there' just so much stacking in general in raid encounters, I don't think a 5% heal will alwasy be worth jumping out of the stack where the AoE healing is happening. Obviously for PvP you will always want it.
Yea glyph of no escape is a pvp glyph only now. Maybe some very rare situations in pve but not likely. Single freezing trap cc, followed by a power shot = gg. And yea it was changed in MoP. Would have been way too op on windlord.
In addition, There also is probably should be a timer so just start prematurely running in so it doesn't catch you off guard and you should be fine then. Also it should be fine for anyone on the main platform, because the people aoeing the nests can live through it.
