Almost all groups want an AlacRev and an QFB. Imagine what a Chrono had to do to provide those boons while a Rev or FB do it in their sleep.
The thing that bothers me most about it is the importance of a FB. You can play QFB with solid power damage in fracts, also can play him with very high condi damage, and as if that wasn't enough, FB is also one of the best healers in the entire game, even without permanent party quickness uptime.
Spin it however you want, he's either too good at too many things at once or other classes are too bad.
But what do you think, how can we break this monopoly? Should Anet nerv these builds, or buff other builds instead, or maybe a mix of both?!
I personally believe that other classes have potential. Reaper, for example, ensures quicknees in shroud for himself, but what if he would share it with up to 5 allied targets. You can find something similar for other classes. Alacrity and quickness maybe should always be shared with at least up to 5 allied targets as this has become so important. I just wish to see groups again that are not built around AlacRev and QFB, without lack of alacrity or quickness.
