why not start everyone in the ba equal. they can use uns to get more stamina when needed, but at least itll gives everyone a chance at first place . its always the same who will place the top, so make it fair for everyone even the players that just started the game a chance. i think this will boost the ba aka more players will play. i know some will not like it , but why not start everyone out the same with the same stuff aka stamina attack and defense, how they play will play it out, or if u can make it where u get skills just for the ba and place them where u want like u get 10 defense, 10 attack 10 stamina, but u get to put the 30 skills where u want them. this will happen every ba so u can play differently each ba and perfect the way you play in time. plus the 30 skills will only be for the ba and the ba only, just a thought.
They have already evened out the playing field in a fashion, by having the overall percentage of your skills allocated to attack, defense, & health determine your strength, defense, and overall health in Battle Arena.
