1/ I've been a 1h/shielder for 7 generation and I've tried dozen of 1h (axe, mace, sword) so I think I'm better qualified than you are to tell if a weapon is OP or not. So far I didn't see any of the advantage you listed using the scimitar, sure it's fast but there are many other weapon as good for a 1 handed, just have a look at
this thread 1h are pretty well balanced imo.
2/ Feinting with scimitar is not easier than with any other weapon with the same speed and it don't hit the head more often than any other weapon, I'm actually having much more glance when I try to hit the head than with my previous weapon: the Niuweidao.
3/ I like to change build and weapon and as I already said I tested dozen of weapon and I'm actually testing Scimitar, what's wrong with it ?
4/ I won most of the duel I did against Casimir with other 1h so far even without shield.
5/ I won't answer to your "ugly part" as I find it quite stupid to bragg about killing a 1h (without shield) when as a polearm user you have a huge advantage (reach, stun, damage...) and you're a feint spammer yourself.
6/ This was never a discussion about whatever is ez mode or a flamethread -> this is not a troll the scimitar users discussion either.
Or, if you want to be brutally effective without any skill, get a schim and a huscarl, facehug and feintspam left/overhead...
list for successful 1h
