Maybe the idea was to make sure theres plenty of legendaries around?

Would they be legendary if they were easy to get?

So many people have them, so many have multiple, theres nothing legendary about them. Also in the name 'legendary' would imply some kind of legend behind the item, but no, they just randomly get crapped out of a lockbox rather than having to work towards earning one.

Plus they have standard stats lol .

I personally loathe a RNG system, mostly because no matter what algorithm is used I have the worst luck... lol
