I feel like I can just barely complete 1 star leves at BW as a 45 THM (I die at least once half the time) and I only get ~3-5k total with bonus + kills. Either I'm bad at the game or soloing is terribly inefficient now. I've even adjusted my spells to accomodate the awful MP costs now like using Stygian Spikes over Shock Spikes. DoTs do sufficient damage, but I literally have to spam heals the entire time and if I have too many resists I die on any pull with more than 1 enemy.
