The answer is…it depends. In you use the old “2:1 rule” for years, then it’s unfair to you. But that rule didn’t make sense before the rariry change, and it makes less sense now. Some people have started using a “3 year rule” where same pets within 3 years can swap fairly. However, you’re looking at a bigger age gap here. Personally, I think a 2 rarity jump more than makes up for the age gap and I wouldn’t hesitate to accept (if you want the pet), but that’s just me. A lot depends on how you personally value year gaps.
