3-star legendaries are the absolute worst. They're worse than worthless, because they get selected in champions and reduce the quality of your teams in champions, which reduces your income and slows your progress. They're obscenely expensive to upgrade, and weaker than 5-star normies to boot. I can't afford to upgrade a fraction of the 3-star legendaries that I get, but the game just keeps raining them down upon me relentlessly, and I'm sick of it.
I've been careful not to claim them from the events that have been getting completed as I play the game, but to my horror the game has been auto-claiming them and dumping them into my harem when the events expire. It's very frustrating.
It would be ok if there was a "bench" that you could put them on so they can't be selected for champions, or if you could just kick them out of your harem, but you can't, and every single one that I get makes my harem weaker and reduces my income in champions because I can't afford to upgrade them.
At the very least the game should allow you not to claim them from events if you inadvertently get them just by playing the game normally.
Please allow us to not claim them if we win them in events, or let us put them on a "bench" away from champions, or let us kick them out of our harems if we want. There's a million ways not to force these worthless girls on players.
Please make it stop.
