There are actually way too many monks these days, can't find a party without at least two of 'em, not to mention all the monk secondaries. I think everyone decided to roll up their monk alts last (like me), and now they're everywhere.
Monk numbers will be skewed down in parties anyways because of how good they are at pairing up with henchmen.
Mesmer's energy pool sucks. Fast casting would only be cool if it decreased the amount of energy it too to cast at the same rate as the cast time - other than that, it is useless. Save 2 seconds on a nuke? Whoopty doo.
Necros even have a better energy pool than Mesmers. Necros are an underestimated support class. I just think too many Necros think they should deal direct damage when they really shouldnt.
Why did you put monks so low on the list? The only reason you don't see them in towns is because they're being botted out in perdition rock or underworld.
most monks you are seeing in those groups are pvp there are almost no pve monks. i made a pve monk which is now lvl 20 and i found that it really would have been a lot easier just to make a pvp monk.
