A "great" warrior doesn't allow someone to charge a beam, a "great" warriors hits the person before he can even move or charge anything. If there's a SSJ Goku charging a kamehameha, you can either try a heroic attempt and suddenly hit him, or you can just beam him to death, totally up to you.
There aren't things like "teh pwner" with weapons. Melee can be perfectly used which makes beams useless. However, if your *cough* great *cough* at hiding and doing *cough* sneak *cough* mapnukes, yeh I suppose your a "pwner" then.
As for your poll, I like melee better.
