Well first off, everyone will run circles around you and you'll have trouble getting in range of competent players. Not too mention that str scales TERRIBLY on 1-handers. For example:
With this build you'll need a relatively long weapon with decent damage. Let's say you go with an Elite Scimitar. It has good length, good speed and decent damage. It's base damage is 31. Now, apply your 88% damage bonus and you're looking at an increase of 27.28 points of damage which will bring you to 58.28 points of damage.
Now, compare it to a current popular 2 hander the Danish. Danish is slower, but MUCH longer which can help you with your low athletics. It's base damage is 40. Now, its 88% damage increase is 35.2 which will bring you to 75.2 damage per swing.
1-handers just don't benefit as much from str builds due to their lower initial damage combined with their slower movement speed due to shield.
So yeah, I think you'll have a shitty time with a build like that.
