It doesn’t make it impossible, but it makes it very hard in high difficulties, it’s no big deal in Legend, but it’s big deal in high Catas and then slap on it even good ping and it’s just, no, screw this weapon, kinda situation.
I played a bit as client in Cata 2 and it was just garbage, if this change was to stay, the weapon would be basically dead for me. I would just take something that I can actually use, move and block with. Halberd felt ok when I did one round with it
Exec was still risky before, and the inability to block was pretty annoying, but it was good and fun to play.
This is even worse, since it’s 1 swing vs 0 swings in many situations 
There is, if landing an attack gets to the point where it’s suddenly huge struggle, that’s a problem.
I used it often on all classes and it was fun on all of em, weapon that is available to all of them, should be playable on all of them, not on 1 with full attack speed focus and only feeling decent when all the buffs are up, that doesn’t sound like good design to me.
The buff is pointless, who needs more crit on lights, nobody, really, you just decapitate stuff if you aim properly. And get SS running just fine anyway.
Yea, this was my main point, before it required precise timing, even when playing as host, now if you try Cata 3 as client … it’s getting just super annoying/ close to impossible, while this issue is not there with other weapons.
As for Cata 3 different, the enemies attack faster on higher difficulties, which is why if you test the weapon in Legend, you might feel like “meh, it’s bit slower but still fine”, while if you try Cata it’s getting bit nastier and if you try Cata 2-3 it’s just complete garbage and you don’t wanna play that at all.
