While I can see why ele3sorc2 would be a good option now, I kinda feel like it’s not as futureproof as warlock 2 is. I’m quite sure that lock3 will out damage sorc 2 with ease once rank 9 hits. (I mean kinda feel like lock and ff will be wizards doppel and fencer now. lol)
It’s also hard to say if rank 9 will have a good follow up for that build or sorcerer in general, or if they plan on making better synergies with sage/enchanter.
Really wish we had more information.
