Cost of reusing X-Factor too expensive

SBxIronman

The bottom line here is that I have spent money to acquire some decent x-factor mods. If I’m using a bonus player during Royale, where I want to use that player in more than one event, the cost to equip the mod quickly becomes so expensive that it is not an option. In essence, you are recharging me (repeatedly) for an item that I have already purchased. If it was a nominal flat fee, I could understand that. But this “increasing cost” model is REALLY unacceptable. I would appreciate if you would review this to improve this aspect of the game.
