Regarding Gacha Drop Rates

So, the drop rate for 4-star characters is 3% for single pulls, regular 10-pulls, and guaranteed 10-pulls. Does this mean it doesn't matter which method I use to pull? I feel like when there were fewer cards in the gacha, I used to get 4-stars more often. Now, even though the drop rate is the same as before, the number of cards has increased, so it feels like the effective drop rate is lower. Also, I feel like I actually get more 4-stars from single pulls, like once a day, rather than desperately doing 10-pulls 💦 It's a bit frustrating that the drop rate for 4-stars is the same for regular pulls and the guaranteed slot. For 3-stars, the rate goes from 8.5% in regular pulls to 97% in the guaranteed slot, but for 4-stars, it stays at 3%... If only 3-star rates are improved and 4-star rates remain unchanged, I wonder if the guaranteed slot even has a purpose? (Feels more like a guaranteed slot for getting 3-stars...) By the way, the rate for featured 4-stars in the guaranteed slot is 0.400%, and each of the 3-star cards is about 0.47...%. I think the reason why the featured 4-star rates feel stingy is because most of the guaranteed slot's rate goes to 3-stars, and the rates for all 4-stars remain the same... I really wish the developers would reconsider the gacha rates soon... At least, I hope they'd differentiate the 4-star drop rate in the guaranteed slot from the regular one 😭
