Yeah I've not had any real luck from the Gacha in this game either... Spent 150 of free flower gems on 3x11 spins. Didn't have a single 5-6* and slightly under average rate of 4* 's. Oh and that 2nd Guaranteed 5* gacha... a second copy of my Lilly, not really one that I wanted more of so just combined her with my original. (Did at least get a skill up)

Still you just have to keep on grinding been slowly pulling more 4* from the seed gacha... maybe one every 50-75k seeds, hard to say don't keep a very good track of my pulls. (Still now have all 3* at 4 Slots and 5/5 skill, started saving the ones that have the same skill as some of the 4*. "Triple Drill, Ground Smash, Flame Burst")
