Druid question about pets and groups

[Megaevils]

So for a Druid who has charmed a pet, if you dont break charm and just run around and kill things, the pet will eat EXP. I hear though if you group, then it doesent eat EXP anymore.

So heres my question, Could you just group with a random guy and run off into a different zone, still grouped, get a pet and solo and not suffer the exp hit?

Sorry if this is a silly question, new to P99 and never got past a lv20 rogue on live.
