A little while ago, when ssj2 was testable for the Betatesters, you could ascend to ssj2. Doing this, it made you invulnerable for the time you transformed. As you might know, those transformations took quite long and you could melee people during it, even though they didn't lose health. And you needed 14 million in ssj, which means you got 28 mil as ssj2.
With ssj2 goku, having a 420 speed, it's quite easy to hit people. If you hit them up you could beat them again before they even reached the ceiling, with just using swoop.
Best part was having one-hit-kill frags with melee, you were that strong and fast you could beat people in one blow. Anyway ssj2 is soon-to-be-up for betatesters again, fixed and added some stuff I believe.
And of course you can't perform 11+ combos with someone who has normal health, I just tested the speed a bit and voila. Normally you would've killed someone with 2/3 blows.
