You even acknowledge that 1hers are the weakest of the holy trinity (2h/pole/1h) of melee.
No, they really aren't. Overall, they're by far the strongest. Their only weakness? Axes, and even then.... you can still have a weapon superior to a katana in your hands after your shield is broken.
Playing a shielder is ridiculously easy, really. Mostly because people just suck so hard vs them, but as a 2hander I'd rather fight two really skilled 2handers at once than one really skilled shielder with a heirloomed sidesword. But yeah, basically you get tons of free kills by just holding RMB, watching and giggling as people run at you with a chambered attack.. then you attack, run forward, score a hit. Then hold RMB again, no matter how skilled the opponent is, it doesn't matter. He can do the most awesome feint ever, you can just rofl as long as your finger doesn't cramp.
But hey, I'm not calling for a nerf. I was just curious to see how hard it can be to play a 1hander after all these requests to buff it/nerf others... and it's not hard, at all. It's just like 2hander minus the need to block (hardest part of the game) and having tons of retards misjudge your range totally.
