Trading Champions
Ok, so this idea has always been in my head since i started the, but wouldn't you like the ability to trade your Champion with someone for their Champion?
Before you flat out disagree with me, lemme explain. Yes, this feature would be a cheap way to ignore the crystals, BUT if there were limits, it could work out, here's my idea of how a trading system in the game should be.
Trading
*unlock at lv 10
*trading cost at least 100 units
*you can only trade once a week
*only characters of the same star level can be traded
*Dueling for the trade, possibly ( similar to borderlands 2, add a little more effort in the trading)
