I apologize for letting the OP die, I promise to update it soon! But I have some questions, and looking through 5 or 6 pages is pretty boresome.
1. Are the EX buff cutthroat midscreen combos still F212 F212 RC 112 xx BF3, or is that other, harder to execute one found by (i think)
@Youphemism the standard now? Also, I do not remember the inputs, but I remember a meterless blade slice was involved.
2. What would the Corner (or screen switch to corner) and midscreen commando combos off 321+3MB? I do not remember ever putting any time or effort into them because I believed that it was not worth any merit, as it was unsafe, less versatile, and less optimal than the Ball Cancel combos, which while they may have required a bit of git gud, were better in every way
