Well, if you stay at distance and use your reach many duelists will refuse to duel you calling you names such as noob, s-key hero, coward... cause it's obvious that long greatswords are meant to be used for face hugging and trying to get into enemy's model where he can't block in most cases
Yeah I agree, 2H is lame because strongest points of that style of fighting are:
- mindless spam or making an invisible barrier instead of learning how to block
- hiltslash or glorified spam technique
- other game mechanics exploits such as mentioned going through the meshes...
Making precise cuts and stabs in the head will grant you whooping 1.2 damage multiplier so why bother... you can become a str spammer which means you can take up to eight normal hits and each one of yours can potentially be lethal for your enemy...
Also forgot to mention famous 180 degree swings which means just keep spamming even if your enemy is behind you're still gonna hit him with full force of your spam...
