Im just wondering why people should take shadow priest over other caster classes. Let´s compare to others (in a view of arenas):
Shadow priest:
Mobility - zero, Fade - its a joke, everyone can just refresh their movement impairing effects on us, and we are done (try to escape from DK, warrior, rogue etc.)
Survivability - well, we have dispersion, but its 5s cd, we can be ccd in that and after this, we dont have anything.
Dmg - ok, it´s the only place we can compare to other casters, we have pretty good damage from dots, but no dot protection here (SnP is again, JOKE!!), spamming mind spike isnt a solution, u gonna get oom very fast if u do it
Mana efficiency - shadow priests go insanely fast oom, especially when they try to heal in arenas
CC - psychic scream (u have to be next to who u want to fear), silence (45s CD) and psychic horror (1,5m CD), only class that doesnt have spammable cc ...
Mage:
Mobility - greatest mobility from all casters, maybe from all classes
Survivability - shields, blinks, 2 ice blocks, evocation
Dmg - insane burst, u all know it
CC - increadible spamming cc, polymorfs, counterspell, frost novas, deep freezes, circle, bla bla bla ...
Mana efficiency - never saw mage who got oom in arena ...
Warlock:
Mobility - same problem as shadow priest, but they have at least portal
Survivability - Healstones, portal, dispel from pet, heal from dots, soul link ...
Dmg - same as shadow priest - dots, but they have great dispel protection - 5s silence + increadible dmg
CC - howl, spammable fear, silence from felhunter, death coil
Mana efficiency - well, no need to explain
So, my question is, where the hell are shadow priests (without friendly dispel now) when we compare them to other casters? We have worst mobility, worst dot protection, worst cc, ... Why to take shadow priest now?
