i wouldn't move cs to rm. RM is super stable where CS isn't. stop trying to fix something that can't be fixed and let it fix itself. either that or try to promote cs (streaming/advertising outside of the voobly client for example) and encourage players to play in the lobby. though a major reason why players also choose not to play in cs is the level of toxicity. people lose interest in playing due to uncontrollable level of toxicity and it is easily avoidable in voobly. comparing to other variety of games, they are punishable and majority of them learn from their errors. find a better way to punish them instead of letting them constantly harassing new players. they will lose interest very fast.

Ive spectated a couple of BF games in the RM lobby and when it comes to toxic behavior there is zero difference between RM and CS

the only difference is that cs ppl is toxic in forums instead ingame.

There's toxicity in RM as well sometimes even worse than what it is in CS.

Gamemodes such as "LN minimun 100 games", "LN FFA", "Regicide", "Michi DM 20min Cut", "LN Nothing" are the ones i've experienced most toxicity from.
People don't seem to quit playing the game though.

Also, they don't seem to tolerate more than 350ms - 400ms & people that are unaware of build orders/strategies (newcomers).

Talking about the 15++ to 17++ rating range which is what i played.

CS forumers are not representing the whole CS community. Most of them not even know there is a forum. There is far more interest to make 3x 9x 256x tech mod rated again for CBA games, than actual CS topics.
