Newbies "copy" other openers because they don't know how to make good ones, and them having a good opener lets them develop their skill (unless the mode is judo when the opener basically wins the battle).

There isn't anything wrong about "copying" a move, and sometimes people will think a guy copied a move because they think they invented it, but someone else found out how to do it too.

Bottom line is that there aren't an infinity of good openers, so people sometimes copy off players who are better then them to get better.

And chrawnus is right, all openers belong to Nabi. :P
