An agi 1h has to be one of the best dueling builds nowadays (dat stab), even with a short weapon. If you have 7+ athletics no one will be able to severely S key you. You can face hug all you want and with a steel pick you won't glance at that range while someone with a longer weapon will. Not to mention that steel picks have infamous ghost reach and are still thin + spammable enough so that you can barely see them. It has the same problem as the spathovaklion... too skinny and small to see. Sure, it might not show it in its stats, but its model gives it a large advantage on its own. I could see the pick being less feasible for a slow str build, but just sit still and don't fall for an opponents S key / kick traps and you can kill him in 1 - 2 hits. Or just you know... use a weapon better suited to your class.
Also, who the heck even plays str crutch 1hander? I honestly can't think of anyone... or at least I have yet to see one as extreme as a str crutch 2h that is something like 36-3. Mostly all 1hs have a decent amount of agi so they can use a shield as well. Most str I know for a fact that a 1h has been using was 24, but coupled with 0 IF and 15 agi (5 ath, 5 shield) they really weren't slow at all.
