There are two arguments that I'm seeing from people who think it should stay.
1. You don't really gain an advantage doing so cause you're standing still and exposed as fuck. Yes this is true, but for the most part TTT is about information; traitors killing people as discreetly as possible. Anyone with half a brain knows shooting someone in the open when someone can see the whole map is a one way ticket to getting kosed.
Okay so deal with the guy in the air then, pretty simple right? If the server is more populated, goodluck finding an isolated spot to killing that guy in the air. If you do and start shooting him, congrats everyone on the server is now converging on your location and you've pretty much outted yourself as a T. If you say something about using silenced weapons, congrats on being retarded, half the maps don't have silenced weapons or are limited to like 1 or 2 for the entire map. If you're gonna say just buy one from T menu, again congrats on being retarded cause most people wont have the credits to afford the silenced weapons let alone the knowledge of how to use the T-menu.
When the server is less populated and there's only 1-2 T's, the innos clumped together can just look at each other and say "yep we didn't kill that guy so we're proven to each other" which again, effectively outs the traitor.
Stealth is just way harder when one person is using an unintended gimmick can cover the entire map.
2. There are rules in place that shut down certain aspects of prop boosting like camping.
Okay and? I don't trust 95% of the playerbase (admins included) to adhere to these rules cause in the few times I have played since its implementation I've seen it broken multiple times by people who lack proper self-regulation.
You're literally forcing traitors into one style of gameplay that gets stale overtime if someone is in the air every single round.
There's a problem that many of you aren't even acknowledging with regards to prop boosting. Most people simply don't know how to do it. Imagine if everyone did this every single round and you have 5+ people in the sky at once. Goodluck being a traitor against that.
I couldn't be bothered less to learn how to freeze a prop mid air so I can use it to parkour around the skybox of a map. People who know how to prop boost inherently have an advantage over new people who don't even know it's a thing, so they wouldn't even think twice about looking in the sky. Especially in a time where the server population is struggling, if I were a new player who wanted to play TTT and saw people playing god in the sky, that would be a huge turnoff cause it just isn't how TTT is supposed to be played. Especially if I died once or twice as a direct result of someone prop boosting.
I get that you guys want to have fun, but that can't come at the expense of server population which relies on people coming back. People familiar with TTT want to play TTT, not duck hunt.
