i'm aware many things have already been brought up/might be in the works, if thats the case for any of them then this post can just serve as a reminder for those. also i dont code or port maps or know anything about how csgo works so im sure many of these things simply arent possible with current cs2, apologies for my ignorance.
remove the thing where after ten rounds of a map it will auto-rtv. either replace it with a set amount of time before it prompts the rtv or extend the 10 rounds to 15 or 20. maps like LA sometimes go by very quickly because of cts dying in the first 30 seconds for 8 out of 10 rounds.
add a bounty system where the t's can individually put a credit bounty on the head of one of the cts which goes to whoever gets the kill on them. could do set amounts like 100/250/1000 or something like that.
add backstab rebel. just make it only be available to select as an option if the t is the last alive on their team if you have to, but lowkey it should just be able to work the same way the current rebel lr does.
add paintball back for bullet hitmarkers to allow for poker and whatnot.
add an option for warden tools to be able to turn off the notification for the t's chat that tells the t which colour they are to allow for a couple more games using that.
fix whatever isnt allowing freezeslap to work as a game as that was always a fun one. i assume this may not be possible on cs2 if it isnt already working but ill put this here anyway.
bring back the normal 9k's of two t's getting their health set rather than the mixup of whatever people do now - yes its true the ct's shouldnt let it get to a point where 9k happens in the first place, but i feel like giving t's 350hp and a deagle (or equivalent) achieves the same goal as straight up slaying @ct which doesnt really feel correct, the round should still have a chance of continuing.
add an option to warden tools/change the current implementation entirely so that blinding the t's actually blinds them fully.
reusing some suggestions from other people; blacklisting the most recent few maps from the rotation, adding gangs, adding a sound cue to jetpack and/or make it non-rechargeable during rounds, make it so you actually need to stick someone with the smoke for it to stick them.
not 100% sure on my stance on this but possibly make it so that changing your skin queues it for the next round. since kos'ing by skin is not yet disallowed to my knowledge, i think it just opens the door for a bit too much risk of freekilling/incorrect kos'ing.
add some kind of slider or something to the !settings so people have the option to turn down the end of round music or the other stuff rather than just having to turn it off completely if its too loud.
if possible, make it so that objects like dodgeballs/wrecking balls/tables/soccer balls are able to be shot with guns and have the same physics applied to them as if they were knifed. allows for a bit more variety with those games.
make a players name instantly show when you look at them when they are on the opposite team, rather than having to look at them for a second or two.
add somewhere a list of all maps currently in rotation and a couple images of each of them would be nice.
