Welp, this beta event certainly is a lot more stable than the first one. I've been able to crank up my settings a pretty good bit compared to the last time. Well, except for Divinity's Reach and the Black Citadel, I have to tune it down a bit there. I have no idea why I have to lower it for those places and not Hoelbrak.
Looks like they changed mesmer illusions around a bit, too. Or maybe I'm crazy.
But it seems like they do a lot more damage than they used to, and it looks like shattering them does less. Which isn't bad, because the first time around it was best to shatter the hell out of them as soon as possible.
I'm dedicating the rest of this BWE to necromancer and engineer.
