It's not going to be abusable, I have a special code I put into my bank file which allows me to use the -ban P1-8 command.
So, like I thought. I gotta hardcode it into my "Banlist". With the IDs, and such. Post weekly updates on who I ban.
@AstralCV - Debuff Idea
To that, I'd have to say no. This would be bad because of trolls and it would decrease my map's overall ratings because of bad reviews. We've all seen those reviews people make on SC2.
My map has friendly fire, because I want realism. It's got a Story mode and Survival mode (like DayZ, where you scavenge items and need food/etc. If you kill a player, it tints your overhead nametag red. If you "Save" a player by applying bandages or anything, your overhead nametag become blue.)
My reason for banning is because some players ruin games by just going into lobbies countless times and trolling. Survival mode is about just running around and surviving. However, people could easily troll the Story mode.
Examples, a group of 3 or more people could join as a party, and simply unequip their weapons. Letting the group falter to a horde of Infected. I'd make sure they do it again in the next lobby if I'm there, and ban them. Blizzard's Terms of Service haven't stopped Frontline NA/EU/etc from using the ban system. If the game detects ANY Bank file editing, it kicks you. NoTD might have some, and a few other maps. Even if they did see it, and people complained about it, I could just email them "Alright, I'll remove it.".
