I'm interested, but I am concerned about having the kind of system that Dark Light is suggesting.
My first concern is how points are gained. In other RPs with systems similar to this it became a grind fest to get more points and killed the rp because hardly anyone would interact with each other. And if they aren't earned through training, then are they gained through participation of the story? If so, how do you judge how many points someone gets? Some characters may not even get the chance to get as much screen time as others and that's just a harsh reality.
My second concern is that that it may hold back the story of the rp. While Dragon Ball Z involves a lot of training, it is also about surpassing one's self in the heat of battle and unlocking something even greater, which would be hard to do if skills are barred behind a point system.
My third concern is that if this rp is open to people to join later far later in the rp then they will be left behind right from the start. Other characters will be far ahead by that point and it will be no fun for others to join.
My fourth concern is the Power Up system. Do you intend to have an actual stat system? If not then those are just arbitrary numbers.
Look, I understand why one would want to have a point system. In theory it should work because it should make everything balanced, but in practice I've seen it kill many promising RPs simply because the system is either too arbitrary, people don't have time to accrue points, or people are simply too greedy and want their characters to become the strongest.
If this was an MMO then this would work great, but I feel like points just do not work simply because unlike an MMO, grinding in a RP grinds it to a halt. It would simply be better to just focus on the story and let other characters have their chance to shine. It would be less of a headache.
