Near the end of last year, Zwei received buffs to its melee attack speed and melee range, well, since then I tried to find some videos of it, but failed miserably...Orz
(no new version video on both olgame and comicat)
So I logged onto KR yesterday and rent one, as well as to check out the nerf it received on w3 just a few days ago.
w1 is really awesome now, honestly I compared it with my 007 both modes, and I think Zwei can finish the 5 hits melee faster (slightly).
The melee range is pretty nice too, you can hit ground/enemy below for all 5 hits, although I did notice that sometimes when you're doing it from certain angles, the 1st hit can't hit enemy that's 2 units' length away like the other 4 hits, but that's kinda rare.
w2 is as usual being smooth as hell, low ammo and slow reload, but honestly, I only cared about the "smooth handling" part.
(beside, isn't this what "normal" Rock should be like? Its range weapon having flaws? Instead of being suits like BD2 or 007...)
About w3's range, well, Zwei's search distance is 3000, while fang's actual lockon range is "slightly" further, possibly about range of 3500
(which is acceptable for a Rock I guess, about the same range of Unicorn's Beam Magnum)
