Excuse me, there is just one major flaw here... no 2h sword has enough pierce damage to "1 hit kill" cav.
Well, in most case this is correct, but you can reasonably expect any cav that managed to come close to you for some reason to have taken an arrow or a bolt.
Futhermore, I'd like to add that I can do this all day long as 2h. And if I'm not that confident, I just block down. Something pikemen can't do anymore trololo.
I wonder why are maul or poleaxe users still allowed to block. Those are more unwieldy than the puny 2,45 m longspears and 3m pikes we have.
Important tool for cav? LOL, no it's just fucking EZ mode like bumping everyone and getting kills without any effort. It SHOULD be removed. If an 1h cav gets me without bumpslash that's what I call skill.
It means that now, 1h cav already had like 0 range (meaning their only kill opportunities are unaware people), but additionaly, if they decide for some reason to attack an aware footman, the footman can recklessly attack while throwing himself under the horse because it means he is invulnerable to the rider. And that is
broken. Moreover, For 1h cav, the simple slash without bump is extremely unreliable, your target can be unaware but move sideways for some reason, it will either result in you missing or bumping thus being interrupted.
When your 2h sword that protects you from cav, is the all around best duelling weapon and weights nearly nothing will cost 30k gold (horse + 1h wep, I forget the shield because I'm kind), we'll talk about EZ mode.
