I'm top 10 2v2 random, I'm certainly not top 10 1v1 material at all. In 2v2 random, usually you play against people who are not so good. So if you are skilled enough, even when the game is not so balanced you can win. Of course you need a competent teammate though.
In this patch though, I really do think playing as USF in 1v1 is a total waste of your time. It doesn't matter how good you are, if you face a skilled OKW on Langreskaya, Kharkov, or Crossing, you will lose every time. The game will start out hard and gradually become impossible, or if you make zero mistakes, it will start out hard and stay hard. I don't think it is really worth the frustration.
I'm not sure it's a complete waste of time playing 1vs1 at every level. You're still improving your play style. Of course sometime people will just abuse and you'll just leave after 5 minutes, but not all of them. Maybe at top50, everyone is abusing the unit to maintain his rank.
But I'm ranked around 800-900 and I have plenty of room to improve and, since I'm pretty confident the abusive unit will be tone down next patch, the improving effect will be double:
- I'll be able to react faster and % of chance to counter the unit and opponent playstyle will simply rise.
- Opponent will need to adapt with the nerfed unit:
1- They stop using it and need to found a new BO in which they feel confident.
2- they still use it and need to change their behaviors toward the unit new capabilities which gives you room to dominate until they forget their old behaviors.
I'm following that same rule when my faction has an OP unit: I try to avoid using it at all cost.
Now if the unit isn't tone down next patch, yes it's time to change faction or game.
