A host should have a right to kick from their boats for whatever reason. Nexon needs to bring that feature back. If I setup a boat and am not happy with the party or am waiting on a friend then I should be able to kick. Remaking a party can take too long. If you're remaking for friends there is still a good chance they won't make the boat since others can join the boat faster. You can ask a player to leave but it doesn't mean they will. Some players just for spite will not leave and/or will keep rejoining if you remake.
I personally am tired of the free level 90 gear people who make no effort to upgrade their gear...even with the cheap accessories...being in my runs. They constantly die and contribute close to nothing to damage which obviously in turn lengthens the run. There are also the players you know afk, don't bring pots blah blah blah. As I said before...if i'm hosting a boat I should have the right to kick whomever I want.
I have chosen to help rid myself of the free level 90 gear people by setting up Hero raids which takes longer but you get another xtra drop and a Hero box. And yes I know I can set battle requirements but I have to do that at the board and people just don't check the board. They want the extra drop and the convenience of joining a run through QB.
Some hosts have resorted to not even hosting anymore due to this change which in turn reduces the amount of boats that are even available for raiding. Nexon please bring back this feature.
