Ah in that scenario yeah i can see why Exo would come in handy.
I dont really pug much as tbh a lot of the people you pug with (on my realm atleast) have no brains about the class they play (example i had a few day's ago when asked to tank for a friend, was a rogue pulling mobs when i was explaining to a friend who had never been there what the abilitys were, ofc the rogue complained about dying a lot and his T8 repair bill, but guess it goes to show dont need brains to wear T8 )
I guess a lot of scenario's like that will make it harder in a sense. I'm just looking at it from a Raid/Heroic point of view and thinking it's not really a "needed" skill as such. Plus the PvP implications would make it a nightmare (prot's are already getting complained about as with the new AD and Holy gear they are nigh on unkillable, which ofcourse people who know the class know that isnt really the case but meh lol)
I just dont think looking at the bigger picture and how much Prot-healers are complained about in pvp now, they will ever let Prot have an instant attack that packs a punch like Exo.
For me i guess i just dont think we do that badly at the mo, we have came a long way since Vanilla (Tankadin? wth is a tankadin!). My main spec is a Ret and yes i know all the "lolret, faceroll" and the rest of it but i've played all three spec's (even to the fact i have three level 80 paladins... damn you dual specs ). I just cant get why people complain so much at an ability that was sort of a luxury to us get's removed. Especially when you look at it overall we have came so far and as blizz have stated nothing is set in stone, thing's can and do change.
