I don't really agree with this. One of the benefits of N wilds is you can turn 10 N wilds into an R wild. If you've got plenty of N gacha tickets and a mountain of pero, it's totally worth it to turn 200-300k of pero into 200-300 N wilds that you can convert into 20-30 R Wilds. If you happen to have a low level Moe card, 20-30 R wilds can be a quick 3000 SED. Since we're in Elite Guard, even small boosts in SED can mean the difference between needing to do another small seduction or not.
I mean, it's super frustrating to have an EG with something like 5k more health than my max SED. Sure, it only takes 5 minutes to regain that focus, but it's so inefficient. I'd rather just one-shot the thing and be looking for the next one.
