These are dark days. Many adventurers quest for the Holy Grail, and almost every single one of them has forged an unholy alliance with Black Knights, Fallen Priests and/or Misshapen Were-Creatures.
When the Knights of the Round Table take the fastest road to power, discarding any semblance of honor, what hope is there for the land?
Seriously, though, it seems a bit odd that the only "free" cards you can grind for that are 4* or greater are evil. I'd like to see events where you have a chance to periodically grind for 3* or greater Camelot and Druid cards as well. Otherwise, you either turn to the dark side, spend a small fortune, or accept that your deck will always be weaker than your peers. You can't win wars when your best Camelot farming opportunity for a long time is just an Armored Warhorse.
I'd like to see a special event like the "Druidic Conclave" or something. A special town that only appears once every month, and only for 48 hours. In that location, you could ONLY get Druid cards to drop, and if you got far enough into the town you'd have the chance to find 3* Druid cards. A 4* Druid Boss would wander around in that area for you to try to get drops from, and if you managed to complete the entire area, you'd earn a 5* Druid for your trouble.
(If that seems like too great a reward, remember that people were given a 5* Guardian Angel just for spending $5 on Gems. If this area was built so there was a dozen areas, every step only advances you 2% and costs 5 energy, and you fight bosses at 33%, 66% and 100% of each area, it'd cost at LEAST $5 in potions to reach the end within that 48 hour time limit!)
There would be a Camelot version of the same event, which would take place once a month when the Druidic Conclave wasn't going on. So you'd have the Druidic Conclave, then two weeks later you'd have a "Rise of Camelot" event, two weeks later back to the Conclave, etc.
Without an option to farm for Camelot/Druid cards, everyone will be trying to save the kingdom while relying on Fenric Gore-claw. And that just doesn't seem right. :D
