The ironite front the arena awards will give several slot purchases each week. That's 20 toons each week to save and upgrade. The gold saved from using ironite to purchase the slots can be used to evolve and upgrade the dupe toons.
I also cannot waste Ironite for anything else than refills. So it will be a "long term motivation" to increase the slots step by step... Nevertheless, I do not understand why a price increase from 1.8 to 5 million was necessary! 277% increase!
