I have just started a thread that is similar to this but more for one event (invitational only) but I honestly prefer this idea. Monthly tournaments, ranked mode for players with over 1000+ wins, it could be exciting. For someone like me who plays Eggwars a lot it becomes boring and redundant after a while so you have to create tasks for yourself, for example, most recently I have started to join team games where I'd be on my own just so the odds would purposely be against me and I'd finally have a challenge. This suggestion would fill that void.
And for those players saying it would split the community, It would not split the community because the normal game mode would still be available to join, you just wouldn't be able to join the ranked game mode if you don't meet the requirements, at that point if you don't it actually BENEFITS you players that don't have those wins because you have something to work towards AND it makes the normal mode easier for you to win. I'm sure you'd be happier to win more games because the hardcore players would be in ranked mode, correct?
But, that's just my theory.
