I have added some extra stuff for Melee already, which I have been working on over the few weeks, which should spice things up a little.
For instance stuff for melee I have been working on is:
1) After a successful Critical hit chance, there is another small chance that the person you hit will automatically Teleport behind you, and also perform a critical hit.
2) Combo is being enhanced.
3) When you Knock out an enemy there is another chance where you will automatically perform a special finisher move.
4) Galactic Donut/Stone Spit/Majin Wrap will have a chance of not working on an enemy.
5) Ki Damages reduced across the board (As well as Ki consumption), to make battle's last longer and more competitive/enjoyable, and hopefully entice more melee fighters.
6) Some new effects, like Screen Flashing, for instance when your Powerlevel gets low, your screen will start flashing Orange, Blue if it's Ki, Red if it's Stamina.
7) People will have to visit all 4 Kai's at least once, before being able to pay to be revived by King Yemma.

Battle Augmentations. - More Details on this as I get farther along.
Somethings that already have been done include:
1) New Transformation effects.
2) Custom Technique.
3) New Icons.
4) Crystal Wanderers on each planet to tell you the location of the Crystals on that particular planet.
5) Some bug fixes.
6) Some new Guild Housing stuff.
There was more, but I forgot. :/
