I dont think so, yes he gets some bits and its hard to get them with high moves but a beat killer get many beats in high, no only 3 or 4 of all sounds.
Nah i know what you mean about bboys mocking the other bboy but the way issei did it just made it seem like he was using it solely for his routine instead of actually mocking blue lol. Eh whatever
Almost every bboy you know, don't know, will meet, and yourself all copy. That first video you watched to learn 6 step, the second video you watched to learn a cc. The move you saw at the last jam you went to that inspired something else. It all started somewhere. As long as you make it your own. Yeah, you take a flare intro and its a bite, but what do you do before and after it? If you in your heart know you didn't purposely steal a combo from a person then you're not a biter no matter what.
Isnt he only like 15/16?? Of course the majority of his moves right NOW are mostly copied from other bboys - a little bit of Taisuke, Hong 10, etc.. but so what? that's how it all starts, in a couple years he'll be the one doing the "innovative" moves that everyone else that comes after him copies..
