I’m relatively new to labbing stuff in training mode, but I got some kind of itch to try to practice stuff, and then one thing lead to another, and now there’s a 4 minute video about Rook’s neutral A.
Note: This set-up will work on Geiger C, Jaina C, Grave C, and Grave ground Super. However, because Grave’s ground super moves his character backwards, your Splash will not end up on the other side of him if he supers.
Also note: specifically against Geiger, he can always ground Super out of either of these set-ups. However, if you’ve cornered Geiger, he does have to recognize whether you’re doing Splash in front or cross-up. If you cross-up and he ground Supers, he’ll end up walking himself further into the corner. Hopefully it’s hard to see the side the Splash is going to hit on!
UPDATE: because it turns out that bA-C gives you the exact same number of frames of KD, you can get the exact same timing for the safe-jumps off that move as this one. The only difference is that bA-C leaves you much closer to your opponent, so you can only get cross-up Splash with this method of timing.
