Interact with Target together with Click to Move only works on things you can click on, such as enemies, vendors, or quest NPCs. If you have a melee team they will run to the target and attack. Most ranged teams will run towards the target and once in range stop and attack. So it works ok while engaged in PvP.

In you're in an outdoor PvP BG where mounts are allowed, you might be able to replace follow with a multiperson mount. You'll have to experiment though I dont know if it will work. Theres a new 5 person mount now the Hive mind.

As far as programs to replace follow, no there is nothing. If they don't want you to do something then finding a work-around to do it would just get you in trouble. Just stick to the basic IWT and Face Target built right into IsBoxer, assuming you're using that software.
