Nah, I say Flower Knight Girls is much fucking easier for beginners than X-Overd

I remember I can still do events back in July 2016 - did get Hypericum and Geranium barely but didn't max them out as I couldn't 3 star the ultimate maps

I manage to do it b/c you had Helper Squads and the Gacha which pumps out 4 star and 3 star knights usually

You can always retreat and keep your stuff especially mining for Hypericum seal stones for the crossover event - that's easier than grinding for eggs
