Everything has been fine and i havent changed anything, i turned on the bot and whenever i get to the rift guardian my dmo wiz just runs away and never attacks. What would be causing this?
Avoidance for bosses is automatic currently, so that's probably it. DMO wiz is really tough though, so I think you'd be safe running with avoidance turned off.
Go to Settings->Combat->Misc and scroll all the way down. You should see the avoidance options there. Uncheck every one of them except 'Attack Mobs in AoE'.
