As the ratio between rare cards and normal cards gets closer to one, the rareness of rare cards decreases. Right now we have two rares per element, plus arctic squid and miracle and the shards. That's 28 rares in a game with only 161 cards in it. So about 17% of all cards are rares. And with weapons being such a vital thing, farms were bound to appear.
But Zanz is against the concept of rare farms. So the question is, how do we increase the value of rare cards, without causing more farms to appear. The arguments:
Option 1: Increase the number of non-rare cards. In this way, rare cards would stop being so necessary, and farms would decrease. It would also be less likely to win rares from spins.
Option 2: Create a new level of rareness called "mythics". Zanz has already said he's thinking about implementing these, and that they could only be won from ridiculously difficult challenges.
Option 3: Allow elemental weapons to be bought, but for 1,500 electrum. These do not necessarily have to be the ones currently in game, perhaps adding more weapons to choose from, but as long as there as the only weapons per element are rare, people are going to farm for them.
Option 4: Remove spins from the Top 50. This would shut down all rare farms, meaning you would have to grind computers to get them.
Option 5: Leave as is. Pretty self explanatory =/
Additional options will be added as they are thought of.
