I wouldn't advise at using that motto. Showing weakness and playing up to it is only going to get you ridicule. Even if you do
suck, don't reveal it. If you have a server, play to your advantages. If you can duel really well but suck at FFA, run a duel server, etc. Also, clan bots are a good idea until you work up a few members. It makes the clan look beefier.
