A question (possibly a dumb question that is common knowledge and I'm just too stupid to know it):
What does "bonus affixes" mean?
EDIT: I might have figured it out - does it just mean the number of random affixes you get after counting the guaranteed ones?
yup. All legendary items have a specific affix (or even special ability) attached to it and then some random ones thrown in there too. This way, even if you find a legendary item, it may not be the most optimal one for you. This will simultaneously make the item hunt longer and harder while almost forcing you to trade (because the likelihood of you getting what you want if almost 0). All of which will preserve the longevity of the game and make items not devalue as fast on the AH
So this is why Legendaries are not as good as rares, they don't have legendary-only attributes. This is good imo, I like finding rares because of the frequency of their drops. Makes it much more exciting to see yellow now
