I think the general consensus is Sorc is one of the weakest classes. For example, look at the unique items added in the latest patch - only the Sorc item has a downside to its unique aspect. The highest tier build I’ve seen for sorc right now I believe is blizzard and that requires the glacial offensive aspect(which is a random drop only vs codex aspect) to work, plus a few other utility aspects to keep your mana up. I had to grind a bit to get a random drop with the blizzard aspect though. Once I changed to that from lightning I had a lot less trouble, and can now solo ancestral dungeons at around my level 75 without getting wrecked. I think at level 100 and high tiers it gets harder because of squishiness since apparently a lot of elites will be able to one shot you without a barrier, but I’m not worried about that yet.
