I honestly think the patch did quite a bit and is helping the balance.
Warrior: It helped get rid of a lot of the broken stun mechanics that could be used. I think stun-locking will still be viable, but not nearly as broken as it was.
Thief: S/D evades are still a bit unreasonable, but their boon strip has been knocked down to 1 for LS which definitely helps. Perhaps we’ll see a pistol main hand build in the meta now for the lockdown (I believe there already was one for condi-damage but I’ve never seen in it a team queue before).
Necromancer: Not a whole lot done aside from QoL things and siphoning. I still believe a previous patch fixed necros mostly; I don’t find them to be broken at all.
Elementalist: Just a lot of changes in general to support ele support. I’m unsure of whether or not they’ll be viable, but I think you’ll see a lot of testing with them and in general more gameplay (for tournaments though? That’s up in the air and will really be determined by what Demise and other ele’s think).
Engineer: Some good buffs for them. I feel like the bomb kit buff was necessary but I think overall they’re pretty strong right now which is good.
As for other classes…I don’t think much changed (edit: aside from ranger, which I didn’t look too deep into aside from pet changes; AND Guardian; lots of good stuff with them that will better their overall play which is great!), which can be good or bad.
I just want to post this so I can see how many people reply with their complaints about broken classes; because right now there is no “one” “God-Like” class that shines above all else.
EDIT: I got a reply for this in another thread about the Warrior. This was in reference to the paralyzation sigil that was absolutely broken, especially on a build like Crysis runs. I think escaping stun-locks like such will be easier, especially with the fix on getting out of launches/knockbacks immediately after you pop your stun break (which was very annoying previously).

Already talked w/ the other balance guys about this, we’ll look at it again!
