2h stab is already the most OP thing out there. You can point blank quite easily, you hold it at the very end of the animation for AGES and it still does a crap ton of damage. I can see lots of agi whores running around with these weapons, which would be sad.
I'd like to see an Estoc, but maybe a 1h variety (like in deluge, very very very fast (above 100) with a similar reach but ONLY stab)
And the pierce damage should not be higher than 28 or 29, as with the length and 2h animations, it would make 2h even more preferable over tin can opening
