A few questions on new characters and a comment :
1. As yamcha seemed to be more melee based, as did some other characters, will there be melee special moves to select, such as the Wolf Fang Fist?
2. Gotenks Kamikaze Ghost Attack. That would be implemented in a similar manner to the Kame Torpedoes? Also, would they use their own independent AI?
3. The characters with one or no transformations, how will they make up for this in the PL department? Will they have an increased rate of PL gain? Perhaps an exponential growth function to allow them to keep up with the PL of transformed characters to some extent?
4. Will Dabura's final transformation be when he is dead, and gets the ghost tail instead of legs?
And a comment on Brolly/Brolli/Broly/Broli
He is supposed to be extremely powerful, and stronger than any other character. Wouldn't it be rather unbalancing to have him then? From what I remember, his PL untransformed is extremely high, higher than an SSJ 2. Also, he is extremely strong and fast, and has powerful attacks.
If included, it would seem that he would become as some would say a "n00b character." You would see tons of brolly's on servers, and the other characters wouldn't have a chance, and it would become quite irritating to many people.
If you weakened him greatly, people would likely complain about how he is weak, and how he should be stronger and able to beat up vegeta/goku/cell/krillin/buu without any trouble. As well, people would most likely post numerous rants about how lame it is that (x) character is able to beat him at melee/beams/bombs/pl gain.
For game purposes, it would seem that you would have to weaken him greatly for any sort of balance, and even then he would probably still be the strongest/fastest character and most used/abused/n00bed/spammed.
