You got an encounter with lots of melee adds pouring from around you?
Mages can freeze some of those away from raid and thus decrease dmg taken by the aoe tanks alot. Also Ranged slows, aoe disorient (oh hai mr aoe caster pack, stop those spells now kk?). decursing aint that bad either (no, your feral tank bear wont swift out to decurse that guy that needs it when he´s got raid boss in his face). Long-range spammable CC that has good duration still beats most of the CC that hybrids can do.
or multiple demons in place? Locks banish&enslave, fear+aoe fear, multiple health+soul stones, curses, their own buffs&debuffs (shadow embrace, blood pact, demonic pact, shadowfury as aoe stun to decrease dmg from aoe packs), durable & self-healing in certain gimmicks (netherspite or such).
both of those also make alot better aoe damage than any hybrid.
need alot of interrupts? can´t go wrong with rogues, and if the mob is stunnable rogues are the best class of all to diminish damage taken by tanks. Wound, mind-numbing and crippling poisons can all be useful in certain fights and haven´t heard anyone complain much about rogues lacking in dps.
Hunters can use frost trap to slow stuff like when we all did dragonhawk adds for first time in ZA, helped me attleast alot. Also like rogues, their dps is top-notch (abit higher than if you go go ret spec when not fully geared anyway if it isn´t your main spec).
And these 2 latter ones can help tank threat quite some which in turn allows all dps to do more damage.
So yes, hybrids do offer their own nice utilities too so i do see hybrids as being the classes that get 3 raid spots more often than pure classes, but more in terms of "hybrids get 3 slots a piece, pure classes get 2" instead of "hybrids get 5 each and then you´ll take a warrior tank so hybrid tanks will qq and more priests"
