I've been played 2h with longsword for 2,5 years. Lately, after a break of 3 months i came back into cRPG with that new stab anim. I wasn't really a stab user unless against horses but now I voluntary use it more often since it's the most efficient attack i got, great damage + great reach.
The lost of spin accel is over-compensated by that Instastab, a bit too much IMO, And not to mention that it's even worse with Great swords..
