I think he needs to learn a LOT more about the game before even thinking about writing a guide. Because he clearly doesn't know anything about the meta builds, and talks about skills being bad because they suck if you're blinded a lot?! Heard of PVE skills? Heard of Asuran Scan? Ignore blind, ignore block, hit away fine? Heard of having condition removal on your heroes?
And LOOOOOL at mesmer elites. Esurge and Panic in "Good" while Crippling Anguish and Migraine is in Great. Laughing at pretty much everything in this bloody guide. It's just so plain wrong I almost wanna cry.
