My mains are Namekian and Majin :P sorry, no SSJ fanboy here.
I'll continue this in the future transformation topic as to prevent going off the skill 101 topic.

While we're on the topic of transformations. Can someone say what stats are affected by the Great Namek and Pure Majin transformations and by how much?

I already got this info for Kaioken and SSJ.

I've read that Giant Namek increases defense etc, making it primarily a tank transformation and not really a healer transformation.

Yeah but I need the specific stat increases. Like how I have for Kaioken and SSJ:

Kaioken x1
Attack Power +20%
Crit Chance x2
Move Speed +10%
LP -115/4sec
EP -150/4sec.

Super Saiyan
Attack Power +50%
Attack Speed +50%
Move Speed +50%
Max EP x2
EP -210/2sec

Cool, sorry can't help you there, You say you also have it for Kaioken? But isn't that one different per class/race that uses it? Would like to see it either way tho :P

and what does keep ugin kioken do? on vids i seen people doing it like 5 times

This:

Kaioken x1
Attack Power +20%
Crit Chance x2
Move Speed +10%
LP -115/4sec
EP -150/4sec

Kaioken x2
Attack Power +20%
Crit Chance x3
Move Speed +10%
LP -115x2/4sec
EP -150/4s.

Kaioken x3
Attack Power +20%
Crit Chance x4
Move Speed +10%
LP -155x3/4sec
EP -150/4s.

Kaioken really rapes your life points doesn't it? >.<

Super Saiyan rapes your EP.

Looks like I won't be using higher levels of the Kaioken. I'll save my SP for something a little more practical.

i'll find out how, i'd prefare using Kioken than SSJ to tell you the truth. really wished they made it a bit more epic, or better yet, the trans for Humans :(
