as you're into it,
- put a real map variety in terms of mod and style (exclude ctf, just in case people think it could be viable).
- do a real COMPETITIVE whitelist, don't ban things for the sake of being boring to play against (Make Pyro Great Again), and ban things that just makes other classes weapons not suitable. If needed i can make a list. (edit : don't need a word i just made it : https://whitelist.tf/9935)
- give space to a larger amount of people having all sort of ideas, not a popularity-based recruitement, almost creating political groups in order to represent this larger amount of players. In order to take decisions on format, maps... Or even give a referendum.
- This idea is crossing my mind, but what you should do to simplify this league is to have only 6vs6 mod, this can be discussed as people would see this as a threat for highlander/ 4vs4...
I insist also about having top players involved in transparency in making this league because "- erynn, samiface, Tino_, tsc, twiikuu" as much as i love your commitment to this game, you guys are not the most competitive players to decide questions about rules format and so on. but don't get me wrong you guys are fully capable to run a proper league, just get help from competitive players.
