Quick note about fighting SSJs in melee head-ons (I probably shouldn't say this)...
It doesn't matter that they are SSJ. Swooping still uses ki. So...if you don't swoop at all until the last second, you can still win a head on.
Killing an SSJ as normal isn't that hard...it's just that the *******s can teleport so much, you can't get a hand on 'em.
On ki spending after transforming: You don't get additional ki. That's unnecessary mathematics. Instead the coders opted to make the moves cost less ki (say, once descended, teleports take half what it would be if you were descended).
This gives the illusion of having more ki transformed, but in reality, you are just using less of the amount of ki with your techniques.
I hope they scale the transformations down a little bit by the later Betas where we have multiple transforms...I mean, an SSJ1 kamehameha ruins the whole server, nevermind an SSJ2 one.
Then again STILL no one has listened to my idea for "weak" and "strong" versions of all the beams, which would better manage the explosion issues...but I guess I'm not in any position to give orders, either way. hehe
