Changes are pretty easy to make, it shouldnt of been behaving as you stated but I did some minor and a few slightly less minor tweaks that should solve the problem, its aiming to balance mana in a conserve phase around 95%, my mage normaly sits around 98% its around a 360ish ilvl.
Weird. My mage is at 365 ilvl right now, and was staying at around 80-85% .. but i was testing on a dummy. I'll try it out in the real world asap.
