Only in single-target situations, which don't occur often enough to justify taking a sub-par talent for any fight that calls for cleave or actually wasting the time or gold to respec on a fight-by-fight basis. ES is much like Holy Wrath, it is far too situational to actually provide much practical use.
Still the best we got...
especially once you consider what our next BiS trinket is in NH.
Anyone got any data on how much it will on average shave off our cooldown?
Well it was bound to happen, I suppose.
ES nerf though boggles my mind, as there is literally zero(or even probably less) reason to pick it after said nerf.
Blizzard balancing 101: do random shit and hf
p.s. This Storm is never gone.
