Maybe, but I've never been in a position where it seemed like a good idea to spend cores on the gacha. I could see doing it to get tanks set to level early game. Having event tanks in the gacha or the loyalty reward would be incentive. Even the last factory slot seems like a better long term investment for generating blueprints, and you need 3000 spare blueprints to elite a single five star. Otherwise spend cores in events where you need to get the last tier of rewards or some emblems. I'm not saying you're wrong but that is a looooong term concern. I still have a dozen event tanks I can't elite for lack of BP, so I'll pass on resetting. When it comes around again maybe I'll be in a better position to get something for those cores.
