I have been playing as a priest in s3-4. My highest rating was 2201 in 3v3, guess as? RMP... Yes the combo was overpowered and such, but atm I play 2v2 with a feral druid, and are around the 2k.. 20k hp n 860 resilience..
The thing is, 80% of our looses are because of me running oom. We have innervate, I run around with my 900 mana chance on crit trinket (works great with penance)
When I am constantly getting punished by hunter, rogue ret paladin dk my mana goes down like fregging wtf fast - my druid spams maim cyclone to keep me alive. Okay I get 10 seconds max of running, and then can do a few seconds of drinking.
A disc priests survival is fairly high tbh, I have no problem staying alive vs. rogues and dk + ret.. Fury warriors seem to rip me but its oke, can get to much to ask x), Pain Suppression tho! Rogue opens on me, I pop pain supressions and wooh blinded. The problem is just we priests are good, but we're like a instance boss - a meele dps can say " Ow yea, hes dead in 40 seconds. Our mobility is bad, and we got no other mana cooldowns than shadow fiend with 5 min not much compared to divine plea. yeye i know it got the healing reduce, but use it at well times n time it - you wont go oom.
And bubble, who cares about bubble. Its predictable, n a good pala wont really have to use it.
