I would personally prefer:
1v1 EW
1v1 DM
1v1 RM
TG RM
(same as @BuckledClub644 )
I dont think we need TGs for DM and EW. These game modes are mostly popular is 1v1s.
Having these ladders as fixed ladders. There might a 5th ladder containing ‘fun game modes’ which change every month. This ladder can have games like Regicide, KotH, BR, … Might even add CBA and stuff like this. But i dont really think this is needed, since these kind of games arent really that popular and still can be played in the lobby if people want to play these kind of games.
But HealFortress really made this thread because of his opinion in the Ban Nomad forever?!?!?!? thread, where he really wants a different ladder for Nomad games, because Nomad in RM settings isnt RM in his opinion. I strongly disagree with that opinion. Nomad as map in RM is just fine. I have still no idea why he Nomad with random map game mode isnt part of the random map game game in his opinion.
