I think you should upload some replays. I've been playing a fair bit of Ost recently in 2v2/3v3/4v4 and while at certain times they are not as strong as the other 3 factions, they are no where near as bad as you make them out to be (feel free to check my win rates / streaks as Ost).
Your pretty much the only person who whines about how bad Ost are. Sure there are other topics but the majority are made by you and you post in every single one.
I along with many others suspect that its a massive L2P issue. Either upload some replays, quit the game or go blob volks like everyone else till Ost is re balanced. I also find it super strange you never complain about obers needing to be nerfed, despite the fact they eat cons even easier than Para's do Grens and they are a core unit and they come with a free lmg and have better grenades and have better vet etc etc etc etc.
