Did you rewrite the description of Esper in Team Builder?
I thought it was something more like a To aru style Esper, rather than a general psychic. Though its possible I misread.
On the one hand, it has more utility now, on the other no super calculations, and no gradual getting better till level 6. Also kinda ruins some themes.
Probably some of my builds would switch from Esper to Speedster.
