Ah whoops maybe it feels like it was lately to me because I started having gem crisis since Blades of Spirit.
But still, I miss the good old days where there are around 30 days to gather gems.
5 days difference might not seems much but if it happens since like july last year you will feel the gem crisis sooner or later.
Especially bad because most of the SR are meta defining.
While I agree that more variety is good. And I actually does not farm every pack. The thing is, card that counter the meta tend to be box SR or UR like Floodgate, Wall of Disruption, Tribute to the Doomed etc.
If they want more variety they also can add more useful card from Roaming Duelist Event or Duel a Thon. The last one that made impact in PvP was Joey which is very long time ago.
