Well technically these haven't been reworked yet.
They did a decent job last update for old skills. They unfucked burning enough that a bunch of fire skills are viable now, Arc and Ele Hit are top tier now, Blade Vortex was buffed to top tier again(it wasn't terrible but wasn't great). Immolate rework is a mixed bag but the skill is average which is better than it was before. Fire Trap is very good now although you can't use it to lvl anymore. Charged Dash and Ground Slam are ok, not great or anything but they're decent enough. Double Strike is pretty good now too. Freezing Pulse is much better, although it still suffers on any maps with doors and shit.
Overall, that's a pretty good amount of skills that weren't not good that are now pretty good or very good. So I'd expect when these get reworked, they might end up pretty good too, although some might fail in the rework.
