I thought it might cock it up, but I wasn't sure- thought I'd defer to experience.
Balance wasn't my concern when considering change. I assume first that any imbalance people perceive in the game is likely either a misreading (or inclarity) of the rules or they haven't figured out how to counter whatever power they believe to be inbalanced.
Overwatch just seems to me to be something people should just be able to do. It's something I could do, and I physically suck. I know this game isn't a simulation but the pay-to-overwatch thing is pretty glaring.
