They could get more users if they gave armors more weapon slots and gave everyone all the weapons for free and let people unlock the other crap.
More maps would keep people interested, when they spend a year breaking the same few maps then do poor remakes of old tribes maps because they can't make a half decent one it is pretty sad.
Instead of making 20 disk launchers they could have had 2 well balanced ones, taking a disk launcher changing the speed the disk moves and changing the colour isn't releasing a new weapon, that is what people do with mods.
