if it was h5 server no one would mind about it, because in h5 mana management is much easier and melee dd are not falling that much early compared to GF. In GF however mages have huge advantage over other classes early on and adding no xp consuming pet will increase the gap even more.
If admins don't remove pets it will show 1 thing, they are scared of other GF project and wants make fast money instead having sustained lon living GF project. It understandable, but for the god sake, current donation list is already on the edge to p2w.. And with pets it would be completely p2w.
