It seems that season 6 has limited the amount of mana that can be generated from basic attacks. The only basic attack that produces much is arc lash and its range and damage are uninspired. In prior seasons I used frost bolt or fire bolt but they generate on minor amounts. I wish I could use spark but it generates nothing. In addition, the truly helpful aspects seem to be missing in action. Come on Blizzard give the Sorceress some love!
You can temper Worldly Stability onto your rings and amulets from very early. I just find a few yellows with OK stats, temper resource gen on them, and then leave them for a good long while until I get a very clear upgrade, then do it again. I also prioritize mana per second when I can, but I don’t worry too much about that. It’s working out OK - can sustain a reasonable amount of Ice Shard spam this way.
