To me, this entire poll falls into one question: How much modding do you (Ame), wants from us, Drivers?
Because if you want Drivers to be sub-mods, then this entire poll wouldn't be necessary. We would have access to the commands, and that's it. The question of /kick being a fun command wouldn't even come into question, since it would be Driver's only "somewhat effective" tool.
However, if you don't want drivers to be "sub-mods", then what's the point in keeping /kick, if /setkick is right there, and it does the same thing, in a much better way?
Which makes me ask the question: Why don't mods use /setkick too for shits and giggles? Is it because it's longer to write than /kick? Or maybe is it because it would undermine the command?
We might never know.
As for /warn and /redirect, well...
As It was stated before, server rules = forum rules, so /warn is okay to leave where it is. I've got no problem in leaving /redirect the way it is too, seeing as it's used so little that I've never seen any problems with the command.
