I'm gonna chuck that bit to the fact that you seem to not read skill descriptions...
My only elite on my level 41 necro is Plague, and I can say it does quite a bit of condition damage, it is definitely better than the Flesh Golem imo, but then I'm biased against minions. Mesmers have Mass Invisibility, which basically cloaks everyone around you, that's not poor by any means. Mesmers also have Time Wrap, which is actually the polar opposite of poor. Quickness is a boon given by, a handful of skills in the game, because it is so OP. Until very recently I thought we didn't have IAS in GW2 because I hadn't seen it yet. The radius of that skill is ridiculous, it applies to all allies in the field, and the combo-field creates confusion. That is most definitely, nothing to sniff at.
For those who may not know what quickness does: "Quickness is an effect that makes all skills and actions twice as fast. Quickness granted by non-elite skills usually comes with some kind of temporary drawback, such as penalty to endurance regeneration or increase in damage taken."
