the sitting by casters is a kissthing, if you have a nav mesh for your zone, they will catch up to you, but yeah they will do the buttschooch till they do.
what alot of us do, i have gathered, is that we have a hotkey with the command /bca //nav id ${Me.ID} that uses nav to move your team to you, no matter where you are on the map.
and then a 2nd key with /bcaa //moveto id ${Me.ID} for using moveutils to call them to you, like if you want to them to move across some water or something that mq2nav doesnt do so well.
with those two keys i move my team around, run my main around and just call my team to me as i need em.
a 3rd key i use on my main is /nav id ${Group.Member[1].ID} that makes my main instantly nav back to my healer, in case i get into trouble and want the mob back at my group.
