Nubee probably realized that it's way too "easy" for a free player to lay their hands on UR cards with all the UR RRs and FAWs, but they wouldn't want to take a step back, so introducing Legendary Rare is the only way to go, haha.

But I do hope we get at least some improvements for inventory management (esp. the ones Seriouzfun suggested below).

Though it would really suck if the "major update" would simply be a compatibility upgrade for iOS 8... lol
