My bad. Missed that. You'd think I learn my lesson about posting before I had coffee.
That is assuming there was not some "look at me" involved in the post in question; either way he was talking about a stunned mob. My point being if it takes melees but a few swings to dispatch of a helpless mobs cooldown timers should be irrelevant.
Gathering a group of mobs, hitting them with /a/ CC spell and a 1 sp Hypno should be all it takes for melees to beat the lot of them into submission or a damage specced caster to explode them and in either case prevent any of them taking much damage. It's still going to be effective.
Toons that can achieve a DC high enough to pull it will be more limited though since it requires lot more grind getting gear, potential TRs and sacrifices in other areas. What I am saying is that those CC specced casters that do manage to achieve a working DC will still have their place in epics.
Where I do agree is that groups likely no longer will be reliant on them due to the combination of limited supply and being able to manage without them.
