As a non-stab 1h player who doesn't feel like he's missing out much with the stab, I am trying to understand people's woes on the 1h stab change recently.
These animations have been changed recently to have better speeds/alignment:
1h stab
1h right swing
polearm overhead
polearm stab
polearm left swing
The 1h stab animation length increase, from what I noticed, helped beat out the non-dedicated stabbing polearms, because by the time the polearm is nearly at full extension, the 1h is closer to middle extension, therefore the 1h can hit earlier at midrange. On the flip side, these polearms have much longer swings with no more "blind spots" like in the past (left swing or overhead = death most of the time), and polearm hits stop the enemy in his tracks. Dedicated stabbing polearms are so long that it doesn't really matter without the 1h player moving much faster. From what I notice, I don't really find any kind of stab easier than the other.
All in all, I don't think it's much of an animation problem, but a stats problem. Some of the 1h stab damages were artificially buffed to compensate for the poor animation. I think that these changes should just be reverted for the longer weapons since the animation is fixed and the old stats were more balanced. The shorter 1h stabs are still damaging, but the natural length is short enough, and they're overshadowed by the current long weapons' damages. That and/or tweak the +3p/+3c heirloom bonus to +3p/+2c.
Changes made:
Espada Eslavona: 30p->31p
101speed->102speed (maybe keep this? Its 25c is pretty bad IMO)
Long Espada Eslavona: 28p->29p
Side Sword-> 100speed->99speed
thrust: 28p->29p
swing: 28c->29c
tl;dr change these back, +3 gives +3p/+3c.
