I watched the game and I don't think it should be voided:
The winning shot was not a sitter, I watched it in super-slow mode and it didn't even stop motion, it rolled perfectly into NJ's worm, it looked like it possibly stopped moving at 0.02s but the rule is 0.25s or more for it to be a sitter, it was lame because it should have been 4s but still wasn't a foul.
In my opinion, and probably every other a2b player would agree with me, Rocket did play pretty lame, his 1st 2 hits were a 3s repeat, and this is more or less the only shot he used, he did try 5s lg a few times, his 3s MaxBounce BackBounce shot that took NJ down to 51 from 80 was actually a very nice shot, it was obviously planned to push him back down the whole, the 4 bar blue wind zook was nice, but the final shot was indeed very lame, but in no way against the rules, that shot could have been 4s.
All in all his 1st 3s grenade hit was a nice shot, the 2nd time it hit it was lame though cuz it was a repeat, apart from the repeat and the last shot he did actually play pretty good and played by the rules, i'd rather get hit with repeat 3s grenades than get hit continously with 4s roller nades that should be 3s.
Anyway, game should stand, he played by the rules and won, no fouls.
