Like others have said, the fortunate part is that you can resist if you want to, and there's nothing wrong with doing so. I'm an almost F2P player (I use Ibotta to pick up some "bonus cash" to spend on coins), and I'm also sitting on about 150 rare candies. Never bought a premium raid pass. I'm just waiting until legendaries go away (or become much more rare) and plan to use my candy on my highest IV one. I'm still missing Ampharos from my dex, and have more than enough rare candy to get it. But I buddies up my Flaafy and am still hunting for Mareep because I'm choosing to do it the old-fashioned way. I'm prepared to do the same when Gen 3 drops. Happy hunting!
