that is my prediction - no more free hero rebalancing or buffs for free across the board. why would they do it when they can just release a buffed up costume for a 
hero and make you pay for it?
you can already see it for Horghal costume - buffed up stats, very similar special - slight reduced damage %, which is countered by increased attack stats, and much stronger attack debuff.
I applaud you, SG, for finding a way to monetize your screw-ups of releasing weak borderline useless heroes!!
