I've always wondered what y'all called a decent playstyle. Do you mean camping Palace on Mirage while on T side and then tell your 10 friends on Discord to rush T spawn when on CT side? Is that it? That will get you kills sure, but you won't win the game if you're playing against good players, not that many of those exist anymore either way. My point is if you want to win games in a server like Rantei$, you better be prepared to stand still on a one way covering palace the whole CT side while you wait for the media bimbos to start their media train from behind. Will you get kills? No. Will you win? Yes. When you switch to T side, all you have to do is rush A ramp with a couple of your mates, plant the bomb and round done. Now you're officially a HvH god!
Enjoy your time playing against people that for some reason were never successful outside of HvH and because of that, HvH is their only source of proudness and joy.
