There aren’t many players where this is an actual issue; there are just a handful of players that are fairly consistent with being troublesome to play with, including:
- very derogative tone (though their words are fine, their tone of voice is demeaning) towards less skilled/newer players or players that aren’t playing how they want.
- Leaving if they don’t like the dungeon (or it could be the group).
- Leaving mid-dungeon if dps is low (dungeon takes more than x minutes), usually with some excuse or another.
- Non-cooperative with the group even when asked (sometimes uncooperative to the point where it causes wipes).
- Extremely insistent on using exploits such as skywalking.
These aren’t even really things worth reporting and I don’t think they are against the ToS (except maybe 5, but that is arguable since many of those exploits are required for actual gameplay), but it is still not fun when you queue up and you just have to reroll the dungeon because your tank (or healer) goes:
Nope, this dungeon takes too long and leaves.
Or five minutes into the dungeon, goes: Oh, sorry, this took too long. I have something else to do.
Or so on.
I’m not trying to suggest a forgive or punish system, just maybe a system to let players have it so that they don’t queue up with someone on their blacklist.
