Please keep thread titles brief and indicative of the actual problem.

Unless your healer is actually engaging in combat, she will constantly be dropping combat. Great for healers looking to get the most out of combat regen, but dropping combat also triggers Jamba's autofollow after combat.

Either disable autofollow after combat on your healer or add/increase the time delay on your healer's autofollow after combat setting. You'll have to set it manually in your healer's Jamba panel since while there's a command to toggle AFAC there doesn't seem to be one for changing the delay settings. Anything between 3 and 5 seconds should be long enough. My healer has it turned off since my follow key also picks up totems and rebuffs, so I use it all the time anyway, and sometimes I just want to keep pulling to the same spot, so it's easier to decide when Iw ant her to follow isntead of when I want her to stay put.
