I also had a poor run of Gem Pulls I did 3x 50 gem pulls and had only received some 4*, I don't remember the exact number now but think I worked out I was just under average based on %. My most recent pull got me a 5* not one I had been chasing (a character quest one) but at least it was one.

I'm now thinking I'll be saving my gems for the future... power creep should see better girls appearing further down the line.

Don't get discouraged, the odds are indeed sucky, but it'll happen sometime. i've been playing since day 1 as a free player and I believe i've done 6 or 7 10+1 pulls so far and I had never got a single 5* until my last pull where I got 3 at once!
So I guess the lesson is: don't get your hopes up everytime you're about to draw from the premim gacha but keep playing and trying and eventually it'll happen. Also, note that buying gems is a very poor investment since it won't garner you anything for sure, so I'd tell you to not waste your money.

This will make 93,5% of rolls from the premium gacha a complete waste and garbage.
