I've never been in a party where the leader would kick one character in favour of one that is considered better. I would only kick someone who didn't do their job, this would be for example a mage that melee'd. The only instance where I could imagine one being kicked to invite another person, would be if the party had nothing but damage dealers and no healer. However, no one should make such a party in the first place.
Also, thieves aren't bad :(, according to some veteran players I know, they're actually one of the best damage dealers endgame. Many daggers have been made stronger too. I have no idea why rangers are getting kicked either, I thought they were good even after the ranged attack nerf. |
