No, it's not just you; I had to re-read the gacha to make sure I wasn't missing something. 300NG for an 11x roll of 3-4* is ridiculous. 700 more NG for one 4-5* is stupid too. 1500 NG for one 5* and a gold skillbloom is...meh on its own; considering that you spend a total of 2500 NG to get that though...hard pass.
Dear devs, no one wants to pay you money for guaranteed units they can get in the free gacha with no chance of getting anything better.
