Guild Wars 2

Drarnor Kunoram.5180:

While necros can’t maintain massive bleed stacks constantly, what we do put on is very quickly replaced at full power if it gets cleansed. Really, Necro is the best for condition damage due to this fact. Their kit is tuned exceptionally well to deal with removal, although a lot of people whine and complain about other classes supposedly being better than us.

Actually, Nemesis stated in several of his builds, he quickly got to the cap of bleeds, so he actually had to choose other things then insane bleeds. Basically, his build is based opon scepter and crits who in 60% also gets bleed, longer bleed duration and such.

In PVE I regularly see Mesmers, Elementalists, and Warriors die in a few seconds, while my Necro stays up for hours and does a ton of damage. Perhaps only the Guardian comes close, to survivability. But the damage of them is much lower.
We Necromancers have death shroud, we can stun break, by far best condition damage, doing lots of nasty things with that.
Only bad thing is light armor, just like Mesmers (but they have clones), and Elementalists. So, if you know your profession well, its great fun.
