This game has major potential to be really good and I would be willing to test further implementations if the devs would be ok with that but if not then this game should reach the height i know it can.
Review: 
Graphics could be worked on quite alot characters and overall.
Music is perfectly fine, from what ive noticed.
The Ultimate type skills i think would be better if it had a short cutscene to catch the eye of the player.
Characters dont seem like a copy of anyone, they have a flair to them, although that may be just me.
For a "open beta" its off to a good start!
