Blue Essence, and some math.

Blue Essence. At my current level its about 16-18 games for a level up. On average a level I gain around 950 Blue Essence. 950 / 17 = 55.88 Summoner Name Change = 13900 BE 248.7473157 Wins in a row to get a name change. There you go now that the hard maths out of the way you can go ahead and balance this greedy new system out.
