I do not pause KA while using the chase function thinking if something broke the follow it wouldn't recover on its own. If I don't want my peeps doing stuff while in chase mode I use /backoff, and that only if I have someone started as Puller. Otherwise I start everyone as Assist, and one as Tank, so the grp fight if we get ganked while traveling.
I have used /afollow (I don't use EQ's follow) with macro paused, and it works well, but I have to remember to do a /bcga //afol off and /bcga //mpause off, which hopefully is hotkeyed, if the grp gets ganked.
If I am dungeon crawling, I use moveutils moveto cmd (with makecamp off and/or camphere off, depending on what mac I am running) to put the grp at certain locs.
There is a
thread that resulted in some good suggestions and hotkey ideas.
