Look at SGE ; it's 90% sch with exacts same potencies and a few differents tools.

Is making the SGE animations and less than 10 abilities taking more that 2 years for a team of a Millions worth game ?

They could take an existing job ; slap new animations on it and switch it's specific ATH upside down and people would enjoy it as long as it looks cool.
