So if you take away the signature weapon of one character & allow the other to keep his, the other guy would win? That's mind blowing breh.
Out of his own mouth he's not a tactician or a strategist, bottom line he's an instinctual fighter with natural gifts that's got a temper. Even before he got flabby he was known for being quick to violence, which is why the warhammer suits him so well. Robert Baratheon is a walking blunt object that will crush anything he can hit.
If you honestly believe that in all Dayne's years and exploits he's never learned to deal with someone using something other than a sword, we really don't have anything to discuss here. The Viper already showed you what happens when a stronger, heavily armored opponent runs into a faster, smarter one.
Robert is getting washed 8 out of 10.
