The thing about revamp is that they changed the Blade Heart effects (Blade Heart = Pride)
Blade Heart now should give a fixed speed bonus (not %). Before revamp it gave no speed (and you can test your version, no speed either). Also with revamp, Normal Attacks (LMB) should recover stamina if you have Blade heart (it didnt happen before revamp, also not working for us)
Another thing about the revamp is the Perfect Cross cut, it's a crosscut with a different animation, and yellow damage (higher damage). It should happen if you try to Cross cut while facing the boss (kinda like Hurk's dodge). But it's not happening.
However if you use the Active skill that makes your Blade Heart buff at max instantly (its one with a blue icon), during it's duration all cross cuts will be perfect no matter what, which is totally not how it works, it should just give you max blade heart for a bigger duration (higher than normal, i think around 30 to 40 seconds instead of the normal 20 seconds for stacking it with attacks) and nothing else.
Also there's a new skill, with an icon identical to the skill I said above, but in Green, it should be Active: Wind Rider, and it's supposed to remove the Blade Heart buff, and depending on how high it is, it should give you SP in return.
I'll take some time to get the recordings going as I can't do them right now, once I'll do them I'll show you side by side with official and nonofficial gameplay
Regarding the Shield Deflection buff, if you successfully deflect an attack with shield deflect, you will get a buff that lasts around 20/30 seconds or so. That buff gets consumed on your next Smash, buffing it's damage (and as result, making the smash damage in yellow). Nothing happens however, the buff stays on the bar forever until expired, and doesn't get consumed by the smashes
Also Slashing High was working properly on the old table, but it stopped working, as well as most other buffs (WW paw, etc), with this very last table
