So spent a couple hours tonight putting together a gear set with more resists and HP, including a few indestructible armor peices, putting my EHP (
EHP calculator here if anyone is interested) at about 115k, while maintaining 50k dps (with SS). I then tried advancing in Act 2, and I am doing surprisingly well against Elites and Champ packs, but I think that is a partially a factor of not coming up against any really bad affix combos.
Found some decent drops, including one level 63 item. If think the drops might offset the repair cost, which is still pretty bad, even with the few invulnerable item upgrades.
Still pissed about Whimsyshire being nerfed all to hell. At least I didn't dump 1mill into the Inferno staff.
