Don't even get me started on bloom dragons. Spent 640 stamina 8 runs to get a purple 100 level one. 7 runs were all exactly 4 20 level ones and single 5 level ones. On last 8th run I finally got 2 100 level ones. So much wasted stamina to have dragons to evolve a single girl. My RNG luck makes me cry.

I could understand such bad luck if there was a real money shop with those dragons, but as far as I know only way to get them via money is FG->stamina->farming dragons.
