A 4-team, hard-coded setup that could work

[Lazortag]

You can actually get up to three different colours for names with the titanium client (one for each team), but not four. You might be able to have it so that everyone who isn't on your team has a red name, but you'd have to ask Secrets.

Releasing Paineel at the start is doable, they did it on this server I think (probably because very few people know the exact make-up of Erudin when Necros were allowed to start there).

Evil humans are definitely way too strong under your setup, but it's an interesting suggestion.
