I can't speak for the other classes but Stormtrance is absolutely not in a good state, it really needs a buff to either base damage or to an Exotic such as Stormdancer's Brace, as even at 10 stacks the damage is still quite pitiful for anything beyond Patrol level enemies. The duration can be extended through Crown of Tempests though a minor extension to the duration wouldn't necessarily be a bad thing, which acts as a counterpart to Geomag Stabilizers. Speaking of, that exotic is so much better than it ever was previously, if you are running an Ionic Trace build such as Coldheart or with Jolt subclass verbs, your super is recharged extremely fast and I rarely have taken them off since they were buffed in Season of the Witch. I would love to see something like Electric/Amplified Armor as a Fragment or an Aspect, especially since it has been an Artifact perk for 2-3 seasons and is generally loved each time. That alone would be sufficient to make up for the lack of healing on the subclass, as orb generation is much easier in my opinion due to the fast ability uptimes.
