I'm leveling up my monk, not 70 yet, but with 370K DPS, 3.5mil toughness, 170K health, 950 all res... my monk still doing great in T1.
My settings:
Monk - Game Guide - Diablo III
There's a check box in Trinity settings/Combat/Misc called "Attempt to collect Health Globes". I've got it checked, but my bot just ignores the health globes, even under low life and globe is very close to him! :(
