I doubt it, I consider stuns a hard control and no blast sets have that as an AOE. Immobilize, sleep, knockback, slows AOEs for blast sets typically.
Beyond the icons in the buff bar and the red rings and icon changes for the affected powers? I thought there was some camera shake, no?
The shake is present with Stone Melee since launch day so I don't consider it too much in Seismic Blast at all, it's fine.
There are a number of side effect systems in the game that players can't control, but the only one I dislike is for Psionic Melee, because like Shockwaves it is supposed to be a selling point of the set beyond theme.
That's interesting to know that Shockwaves will ignore sleeping targets. That's actually pretty cool!
I've mentioned Upthrust obscuring/being a bit obnoxious but the rest I am ok with including Tombstone. Also mentioned Upthrust and Meteor taking too long several times, so it is nice to hear others chime in on that. I never really noticed a damage problem outside of earlier build's Rock Shards and a bug with Meteor early on, as I figured it's probably in line with the resists I expect. I admittedly didn't check the math and mostly gave it a run for its overall feel.
