Krazy-Killa, if I am Goku at 1.8 mil and I am fighting buu who is at 2.75 mil, the only thing that would prevent me from slamming him into the ground and kiblasting him to oblivion is skill. If he sucks, i'll kick his ass, if he is average, i'll kick his ass, but if he is very skilled, he will rip me to peices. You have a very distorted view on what PL affects. In a melee fight, PL affects how much damage you do and take. If your good this won't matter, other than it taking a little bit longer for you to kill him, 'cause your attacks will do less damage. The only thing PL is the #1 deciding factor is in struggles. If you got into a struggle with buu in your scenario, you would die, plain and simple. But otherwise buu would just be an easy way to increse my PL even more. Then, once you kill him, if you want transform, do it.
