New team

I have a Paladin, a Rogue, a Warlock, and a Mage running as my group. . .

I've managed to get by so far by just spamming "1"... but I need to get a little more intricate here. So, I'm looking for advice. Also, whenever my rogue starts "stabbing" it breaks auto follow and I need to shift+ctrl+f twice to bring him back to party...

How do you guys work multi-class boxes?

Thanks for advice!
