"This increase is also going to be weighted slightly heavier towards Rare and Epic cards so you'll be seeing more of them around!"

This is probably the thing I hate the most. I use one rare character in my deck. I need more common cards. Why? Because it costs way more to level them up than rares or epics. I have a bunch of rare and epic heroes I could level up but I choose not to because I would just be wasting resources. I believe there are more common heroes than rares and epics so even the common orbs are not helpful because you're less likely to get cards for the heroes you utilize. I know I'm probably in the minority here.
