I mostly played 1v1s in vCoH. But right now, I don't enjoy them that much for some reason. 2v2 on the other hand have become alot more fun
Maybe it's the 'lack' of 'rewards' for microing well. Which is more important in 1v1s then in 2v2s. In 2v2s it's more about teamwork and that is still fun if it goes well
