That would work if I was the tank or the monk/sk puller, however as a cleric or any other non tank class would get their butt handed by a bad pull.

Yup, I've seen the pets running back and forth. I thought it was just a quirk with bot pets. The only "pet classes" I have in my bots are enchanters, shamans, and 1 Shadow Knight. ~Most~ of the time the SK is in there tanking as much as he can. The Shaman and Enchanter pets are the ones usually running back and forth for me.

up on closer look, the problem occur at the scope of fighting. right now, the rules are set like this :

FIGHT BEGIN :
BOT) stop moving
BOT melee) if have LOS, move to mob and attack
else, stand and do nothing
BOT caster) if have LOS and mob distance < spell range, nuke/debuff/dot
else, stand and do nothing
BOT healer) if have LOS with melee, heal
else, stand and do nothing
BOT pet) if no LOS with MOB, attack anyway, pet can walk thought walls ... -_-;;
if mob distance < pet/master, move and attack
else, run back and forth from master to mob
FIGHT END

I think the problems is the else part, need more work in there, like ...
melee ) if no LOS with mob, move to me
caster ) if no LOS with mob || mob too far, move to me
healer ) if no LOS with melee || move to me
pet class) if mob too far, move to me ......

maybe this will help ???

the bots will run through walls too. just do the PoN Hedge maze event and you'll see it clear as day...

Though, I did notice a while back that my bots generally had no troubles keeping up with me in lower guk (before i got my own SoW and Run Speed AA later). I almost never had to summon them when i was at base run speed.
