this is why I propose to extend the duration of both 2p and 4p to make the more usefull.Considering the normal ilevel of next tier seems to be 541, most people will be at 545+ if they are raiding in a raiding guild, and this is a raiding set bonus we are talking abt.

Considering how fire plays atm, even at sub 50% crit rates I wouldnt see much use for this. Unless the proc also prevent from IB to go to cooldown when used, then it might be usable, but the tier bonus says no such thing.
Also the 2 set is really annoying if anything.. 4 second refresh timer. That means if we get a nerf to CM, that means we wouldn't use the tier at all.. cause you need to launch a Pyro <4 seconds each time. And ye that means we have 2 fireballs each time if we can get the cast to under 1.5 seconds with the buff, so the 2 set is really really RNG based, which is the last thing fire needs atm.
And the 2 set also encourages mages to do the HS+HU rotation to keep the haste going for longer period of times and to stack it. Which inturn makes the 4-set even more useless for those mages who wouldn't use HS+HU rotation otherwise.
