So, here are my findings so far and I stress this is after, literally, 10 minutes:
- Bot spawns with negative health [confirmed]
- Bot attempts to heal itself - sometimes works and sometimes does nothing
- Occasionally (frequency not yet tested), #bot group attack does nothing. The bot faces the target, perhaps gets hit by it, but doesn't attack [happened once so far]
- Bot randomly camps for no reason (Has now happened several times, in the middle of a fight - forced to wait full respawn time before bot can be spawned again) - After testing further this seems to happen when the bot gets hit by a mob.
- Ranger bot (perhaps others too) still often refuses to heal me if I have regeneration spells on. In fact, clicking off the spell still doesn't appear to work (this is worse than it used to be). He just healed me once, at 60% but refused to do so at any other time, even when almost dead in a fight. His healing has an extensive delay to it... waits ages between heals. All very erratic and alot worse than it was pre-patch
- Addition to above item: Ranger let me die rather than heal me when fighting a ton of greens (so the death was very, very slow). Clicking off regen made him put it back on me! This is when I'm at 40% health... At least before the patch, this made him spam heals on me which actually worked. Ranger bot is definitely worse than before patch
I'll keep adding to the list as I go.
