Propagandalf: First let me say I still hate you
You're a very good player and I usually run away when I see you
You still eat me (some of my often used names: ARROW/B613/"no name") anyway.
Second: I totally agree with you! I've been thinking about no-names no-colors too, but already it's hard to see who's who when someone with the same color and a lot of blobs gets close or on top of my blobs. But currently I enjoy attacking those teams more than winning...
LOL! I am flattered
In theory there is nothing wrong with having teams in a game, but only if everyone were in teams, or if players could choose between a single-player mode or team mode. For instance, if it became illegal to team up in the single-player mode, you could ban people if they were proven to be teaming. If there were two game modes, it could remove the teamers' incentive to spoil the single-player mode.
Very hard to stop people helping others in individual mode and there is probably a fine line between helping someone out and creating a team at times. Would need a very good admin to judge. Part of the fun is having the power to help or not help people.
It's easy to stop them, just ban them. However, I agree with you that part of the fun is having the power to help or not. With that said I don't think it is necessary to have crackdowns on all kinds of teamwork. I don't mind people helping each other by shooting gears all over the place, but there is one particular move that is extremely unfair: When several players suddenly sacrifice themselves and merge into a huge blob, effectively eating anything in their immediate surroundings. If you think about it, the devs already tried to prevent this by making the mass you shoot out NOT increase the size of other players.
So, if the same players continuously do the team-kamikaze move, they could for instance get a warning and finally a ban. Like you said, a good admin to judge would be necessary, and so video proof to mods will help. If you provide say 10+ video clips showing the same offence (easily recordable within a couple of matches), it is not so hard to judge anymore.
I don't see how this can be a negative thing, it will just make the game fair again and a "deadly game of wits" as it claims to be.
