Ele
IMO, diamond skin is fine, it’s the sustain from other sources that makes the class unreasonable. It’s impossible to get/keep the ele below 90% due to the constant protection uptime (which is 20% more effective, plus the -10% dmg from frost aura, making burst impossible), heal spam, and condi cleanse. The real culprit here is the “aura,” and the number of easy, powerful synergies which can apply to it.
Elemental shielding should have its own damage mitigation buff of at most 20% (more reasonably 10 or 15). Keep in mind bastion still gives frost aura, another -10%, and I think the regen of torrents should be moved to bastion, eliminating the spammable heal entirely.
Having a trait with both an ICD and a no-ICD for two different simultaneous benefits is counter intuitive. Vigor on its own is plenty powerful, especially since it provides extra endurance with latent stamina, allowing for more frequent dodges (damage mitigation). Adding a damage mitigation buff on dodge for hardy conduit (non-stacking duration) would foster more active play.
Of course, an alternative is to remove the auras from shouts and replace them with another mechanic.
Scrap
I main Scrapper, and will tell you that it is OP, but healing turret isn’t really the problem. It’s very easy to interrupt, and with all the CC flying around I find most often my enemies probably don’t even realize they’ve interrupted it. Considering the actual heal you want is its active, with a water field that you can blast, and not the initial heal, the results are already delayed beyond the tooltip. Sneak gyro really isn’t that great either (although a longer cooldown is completely reasonable). Mortar has much more utility.
What needs a nerf is slick shoes, which puts down absolutely crazy CC, and hammer itself (either damage nerf, or its reflect/block durations need to be shortened/cooldowns increased, or both. also, thunderclap should be a light field, not a lightning field, as the instant, ranged stun is already powerful enough, following it up with three immediate dazes from the successive leaps is a bit much).
Also, rapid regeneration is a little silly. It should either give a one-time heal on application with an ICD, or a different effect (vigor? endurance maybe? idunno)
Chrono
Probably.
DH
Traps need to go on CD when they are triggered (if this is already the case then it must be bugged, because I’ve fought DH who have chained the same traps back to back as if it wasn’t), and need a major damage nerf. Compare DH traps to every other class’s trap in the game and they are on a completely different playing field. No “skill” which requires so little should be rewarded with so much damage. They also need much more dramatic visual cues (often they are literally invisible) and either the daze on trigger trait needs to go, or VoJ active does. Fighting two DH after using all your dodges on traps is like being a pinball until you die.
LB#2 also needs either a damage nerf, or a CD increase.
Herald
CD increase is reasonable, but the 7th strike doesn’t make that much of a difference. I think it just needs a faster cast time, so that a single dodge will negate much more potential damage (like the change to ranger’s LB rapid fire).
Reaper
Yeah.
Druid
The 1s daze on swap isn’t a big issue.. a bigger one is the 2s daze on kitten cooldown with lunar impact. That needs to be removed entirely unless the CD of the skill is increased. It could possibly be moved to Natural Convergence which has a 10sec CD but a 2.5sec cast time.
DD
Impact strike needs the daze and launch removed. It’s a little much when it can already basically insta-kill you when downed, it needs at least a teeny chance for counter-play.
