I honestly think that Mid-combo slam attacks should be removed entirely, and the jump-then-slam mechanic could be refined further.
With a new member on the list, the Two-Handed Nikana, the list of melee weapons with crappy comboes continue. And I won't lie, I don't like experimenting with stance mods. Mostly what interests me is the reach or angle of the attacks, and their speed.
Many stances have comboes with high hit count, but end with a slam, or have one mid-combo. And i think this is just awful.
These slams disorient the player with effects, and also ragdollize enemies which always does more harm than good. They become harder to target or fly the hell away, so the combo on them can no longer continue. The whole slamming mechanic just feels all messy.
Speaking of messy, when we talk about the slam from air, the damage dealt to enemies shouldn't be this terribly low, or have this huge falloff. It pretty much diminishes the offensive capabilities of the slam attack and just makes it into a fast method of stylish falling.
I'd be very happy to see these flaws tweaked in the upcoming phases!
