Memorial Fragment Acquisition Conditions

So you get 1 fragment for ☆2, 15 for ☆3, and only 1 for ☆4? Does this mean you have to pull a ton in the gacha to exchange for ☆4? 🤔 (500 💎 needed for ☆4 exchange) (Image 1 shows fragments obtained from 190 pulls in Blue Fes) I think they should at least give 15 or more fragments for ☆4 too, getting just 1 for ☆4 is a bit much, isn't it? 😧 What's the point of collecting fragments??? ☆4s can be obtained from the gacha, and Blue Fes PU has double the drop rate (currently boosted acquisition rate), right? Why only 1 for ☆4??? Isn't it a huge loss to get a ☆4 from the gacha?? If we calculate with the 10-pull minimum guarantee (1 ☆3) and 300 pulls (pity), you get 450 fragments, which isn't enough for a ☆4 exchange. So, if you want to exchange for a ☆4, it's expected you'll need over 300 pulls. For an anniversary campaign, making it mandatory to pay to exchange for a ☆4 is just too harsh 😭 While excessive generosity isn't ideal, if you're advertising ☆4 exchanges, shouldn't the acquisition amount be adjusted a bit more? 🤔 I saw some people happily looking forward to pulling in the gacha and possibly exchanging for a ☆4 based on the preview, but if it requires paying or reaching pity, isn't that just sad? I'm not aiming for the ☆4 exchange myself, so it's fine for me though ↓↓ (to be continued)
