Basically, if you look at your rules page as it stands now, the entire first paragraph is flawed and Ill tell you why.
The league is here to facilitate matches played by the clans. As such, we are not here to impose a myriad of restrictions which WE think will make the league fun and balanced.
Right away you are lowering the quality of the league. The league
should be what you (or we, cuz I'm helping right?
) think is fair and balanced. Hopefully fun too, but if its fair and balanced that should take care of fun as well. Thats not to say that you should say "You MUST do this, you MUST do that, you MUST NOT do this, etc", but at the same time you shouldn't let the rules be ran by the clans. If you want every clan to have a say, everyone vote and form rules and restrictions before the league starts, not on a match-to-match basis.
DP clans have been matching for a long time and basically know what to do.
If you have actually played matches against most of the clans that play these days, you would know that this isn't true. Clans know how to
play, but most don't know how to properly match. I constantly have clans asking me for 2v2 matches. You need to have a bunch of rules (not really rules but just guidelines) for matching just to make sure everyone is on the same page. This will mostly be common-sense that everyone should know and follow already, such as only one team joining their color and then the other team joins after everyone from the first team joins. Everyone should know that already, but you will be surprised how many clans don't. And thats not really a rule, its just something that makes matching more organized and run smoothly.
There are a few rules, such as minimum team size and map restrictions which we think are absolutely necessary.
You absolutely need rules dealing with format, but you also need rules that ensure competitive balance. And thats where I think most clans/people don't regularly follow in non-league matching and don't even comprehend or understand to begin with. Things like regulated maps will help to keep matches fair and balanced. If each match, which is weighted equally, are unbalanced because each one is played completely differently, then you don't really have a league. Its more just a ranking system and you might as well just run a ladder instead.
Otherwise, it is up to the clans themselves to play fair and balanced and have fun.
Again, if you leave it up to the clans themselves, it probably won't actually happen. There will always be the clan that tries to bend the rules towards their favor. The more you leave it up to the clans the more conflicts will arise. And even if both clans completely agree to every stipulation in their match and both feel it was completely fair and balanced, that does not necessarily mean its fair and balanced with the rest of the matches in the league, which is the purpose of the league in the first place.
If a clan is found to be disruptive, it will be removed.
Nothing I can find wrong here, its the only thing in this paragraph that is right
But seriously, the only thing you need to be careful with is to not be too lenient on this. Of course you also don't want to jump the gun and kick a clan out for some small and minor disruption. If you outline specific and thorough rules to begin with, this will make it easier for clans to know how to act and what will or won't get them in trouble. Then they will have no right to complain if they screw up.
