If that's a common rule, then they need to start frickin following it, because if I stay in the dungeon it's because I wasn't the last one in there, if I join and I see 4 people already I always automatically leave and continue to try and join another.
So, tell me why am I the first one kicked when I'm not the last one to join?
Forgot to add exception to the rule that I mention.
"5th person joined has to have the courtesy to leave as long as the group does not have a cleric, unless the 5th person is "useful" and there exist a "useless" class in the group, for which the kicked target will be swapped."
But, let's not call it a rule, because it isn't technically a rule, it's more like a community developed ways of playing dungeons. It is just like in a swimming pool, you are supposed to go forward on the right side and backward on the left side, and if your swimming speed exceed the average of the swimmer, either too slow or too fast, you have to have the courtesy to move to the other lines. None of these are actually rules, but more like a community developed ways of doing things.
You paid for entrance fee for swimming pool, does not mean you can swim in the line too slow or too fast, if you want to do that, go to the shallow pool.
Same thing for dungeons, you paid for entrance energy, does not mean you can stay because your scout is useless (sorry lol), if you want to play scouts in dungeons, do it with a group of friends.
The kick function has to stay, because if there is none, people will go afk which is not good. See in PvP games like CD, DP, where there is no kick option, and when you see people go afk, how disturbing it is to you?
It's more like the same thing we've wished for long, all sort of game arena whether PvP or PvM, there has to be some sort of reserved slot for clerics, because ROSE online is still a game that you need a cleric to proceed. (unless artisan class can finally do the buffing job)
