I was playing a match as Kleese against Benedict, and we were constantly getting into long range firefights. I wasn’t super worried, but while firing at him with my wrist cannon I discovered something.
You can shoot Benedict’s rockets out of the air.
Knowing this, Benedict is nigh upon a non-threat when facing any ranged character head on. Simply shoot the rockets, shoot Ben rinse and repeat. This may help you fight post-buff Ben (who isn’t really all that much stronger) if you’re having trouble.
