The goal in mind was to make SSJ, Pure Majin, and Great Namek equal in power and, to some extent, usage to Kaio-Ken at 3 SP, not flat out replace the skill. This is why I felt CD shouldn't change since it would result in people spamming the hell out of the forms and ignore using Kaio-Ken. It also maintains the balance to these forms since they give better boosts than Kaio-Ken. Now granted Kaio-Ken can and should be used if you need a quick power and crit boost for, say, powerful bosses or being able to heal/buff without losing power while the transformations should be more towards needing a longer power boost duration for long dungeons and TMQ. Both forms can be useful in PvP as well if you really need that extra kick (like in later fights in Budokai for example).
lol Fair enough I suppose.
Then why would my turtle use Super saiyan if Kaioken is just better for him. Remember that transformations have a huge cooldown, should that be changed too? I always thought transformations at huge cooldown should be very strong for its duration ( I giving super saiyans a time limite like the other transformations have).
