Hero Academy! Can we please have more information?

Summons done right in a similar game who are not so tight on earning daily gems for your summons. 100 summons=Guaranteed Legendary, among the other items you earn while hitting the 100 mark to level your heroes. I have saved my gems for bout 3 months and am sitting at 60k plus. On top of all that when you pull heroes you don’t need etc you can turn them i to fodder for heroes you wanna level. SG could learn a thing or 2 on how to treat their FTP players from this company.

Comparative analysis of games is very useful, just please explain rather than including screenshots. Thanks!
