Guild Wars 2

How do you guys beat mesmers?
I’ve got a build with lots of ae, and indeed also a lot of automatic ae, ie. bleed on weapon swap, enfeebling blood on DS, and mark on dodge. But I can’t seem to beat good mesmers. In reality I am beginning to come to terms with the fact that you can’t beat every class with any one given spec, but I’d like to know if there are things I can do to improve upon.
My spec is 10/20/10/10/20 for terror dmg and +50% duration. This is actually an offshoot of Sheobix’s feralmancer build, changed for my taste. I run staff/scepter/dagger.
I’ve got a few ptv armor pieces so far, and rest are rampager armor/weapons/jewels.

But even with my ae bleeds and marks, I just can’t seem to down the really good mesmers. In fact I met one in wv3 today that still had like 90% life after he downed me :S
So, any suggestions? And did I leave any important information out when asking this age-old question?

I only really lose to mesmers if I screw up and don’t dodge the blurred frenzy/shatter combo (either out of endurance or fighting someone else). Of course I might not be facing good mesmers either.
AoE conditions + epidemic with 20% less cooldown. You will either load the condis up on the illusions ruining his shatters/heals or you will double up on the mesmer.
I’m also a big fan of since we have no buffs really to speak of stand in the chaos storm and wail on the chaos armor before corrupt boon/putrid mark and send all his big cooldowns right back at him.
