Id rather ban the Solemn Vow than the Iron Bomber, if we were just banning two.
Seems so odd to me that a weapon is allowed that basically negates a not insignificant amount of game intelligence and gives free info in a lot of cases. Sure a good medic should know the ubers, but there are times when it can be lost or you're not sure how well the enemy have built. Knowing enemy health is crazy too.
Yeah an ubersaw gives some uber, but you might use that once or twice a match at most. The Solemn Vow you can use every fight or stalemate. You could argue that both meds will be using it, but why make the game less cerebral?
Feel free to convince me otherwise.
