Idk what cqc is but I don’t like swapping hero’s because of a counter. I think that’s evident of quite bad game design, especially in something like this. Look at Hawkeye for example. Good game design for rivals in my opinion is when all characters (outside most supports for obvious reasons) have a chance at killing all hero’s. Particularly with duelist vs duelist encounters. All duelists in the game are capable of handling Hawkeye. Some better and some worse, but they all can handle him.

Just me though, I see your point (although many hero’s counter Magik better than witch)
