Capcom has transcended into next level memer and silliness. They literally patched the unofficial netcode made by fans for SFV that actually surpassed Capcom's initial official netcode.
So TN themselves confirmed that unholdables are a glitch in their patch notes. But even so, back dash cancel is also a technical glitch that devs are ok with it so hopefully it's not removed entirely in the future.
I swear this wasn't possible before... but the latest patch basically lets you rag people around on the ground like a puck on ice? Having fun extending my Tina's combos using 6K and 2KKK... lol. Havent come across any downside yet, personally.
Lowain from GBVS is an incredible memer along with the bros. Truly legendary. One of the best characters made, fighting games need more characters like these lol:
