Chronomancer barely has any damage and Stormweaver is old and fairly powercrept plus somewhat niche due to element/ailment focus, with Bloodmage also nerfed and Infernalist being somewhat quirky, it makes some sense. A lot of alt qualities aren't very interesting, but that doesn't mean they're not super strong, stuff like more chains, more aoe, more proj, less duration(on stuff that you want less on to make them pop instantly) and so on, boring but turns good especially since your whole build gets high quality stuff.
Only downside is you need Split Personality because pathing in PoE2 is kinda dogshit but well once you have the jewel it's not much of a downside.
Gemling has a lot of cool builds this patch, I didn't think it'd turn out this good but there's a lot of interesting skills. And you can level/early gear as a Tactician for league launch and swap later which is also nice.
