Well, you see:
2h is the master race, and has thus been declared by the Developers and a large portion of the community.
2h is the master race and will forever be buffed, ur al gey fite m irl i train ufc
So, of course they have better animations, weapons, damage, and speed. I mean, every game has to have something similar.
Seriously though, I don't think the 'problems' with two handers come from developer bias, but I do think it has a strong community bias considering a large portion of the game was proven to use two handers. I thought that maybe the addition of nudge would throw some of that off, but after witnessing Bumblebee switch to a long dagger, nudge, and then back to a +3 longsword in the matter of a second or two, I figured that hope went down the drain.
Two Handed animations are currently the 'best', and I don't mean that they look the best or seem to be the best, they literally seem to have the largest advantage over any of the other weapon types. The stab animation, even before the change, was fucking ludicrous, it was like reaching across the entire galaxy with the start speed of the Millennium Falcon and ending with the speed of a slug slowly drowning itself in a pool of super glue and morphine; yet it still held the power to black bar you in one hit. I still experience this with the new 2h stab animation, but not as much.
The swing animations for 2h are:
Shorter, but much easier to turn with and almost never glances.
The other swing animation is
Longer, harder to turn with but still almost never glances.
The relative distance between the pommel stone of your sword and the tip of the sword when compared to the location of your enemy holds no factor in how much damage is dealt. Top this off with the fact that unless you're a straight agi-build they'll easily out speed you in just about any situation and you've got yourself a good old fashioned turd sandwich of a game.
Yet, for some reason, we keep coming back.
