This build is just bad...
If you think that build is bad, then you sir, are bad.
After 17 gens of 1-hander I assure you it is far superior to the standard 21/15 build.
With 6 PS you won't glance unless you mess up your footwork. It's also enough damage to put anyone down pretty quickly. Especially combined with the speed bonus from 7 athletics.
With 6 shield skill my MW Heavy Round never breaks.
With 7 athletics I don't get surrounded, can pick my own battles and can catch archers.
And with 0 WM I don't waste points on something you don't need as a 1-hander. With 111 WPF I still spam the shit out of people all day long.
With this build, you do need to know what you're doing but if you do, it's WAY the fuck better than the standard 21/15.
