I know if an alt got to the top tier he would be highly skilled, as that is how the system i said works, many alts are extremely high skilled. The reason to stop alts is nothing to do with farming or that it is just because people have that stigma against them. People in general hate them and don't think they should be allowed, often because they are banned players.
Yes maybe you are correct, and the alts thing and QI restriction should just be forgotten about. It was just a point to keep people happy.
possible implementation
Reset elo, create ranked servers (black belt and up) of some main mods with a few of them being on monthly rotation. Only in ranked servers would it be possible for you to get global and mod ranking. Every problem solved.
^Doubt you could do that without seeing what kind of variables the Toribash server uses to determine ranking.
To be honest, I'd like to see the code. If someone could send the relevant segment to me I could take a crack at it.
The problem with Elo applied to a game like Toribash is that the system itself was made for Chess, a game with no random factors whatsoever. TB is just too chaotic with all the random fracs and inconsistent damage values across the board (10k rub damage ftw). It's also a lot easier to lose a game of Toribash than it is to lose a game of Chess when players of hugely disproportionate skill levels match up with each other.
I gave some thought to this, but I couldn't really come up with anything better to gauge players under vanilla circumstances. When I want to see how good people are, I just check what mods they play, their belt and their win rate, which tells me pretty much everything I need to know.
