This would make sense if Plarium wanted lower sales of Void shards, and I would love better summoning rates too but I am guessing this is counter to the current business model... or any potential business model.
I disagree - change the summoning rates to be better for void sales - more people would be willing to buy them since it's already more expensive to buy a void shard than an ancient shard. Instead of summonning 200, summon 100 before chances go up - which is still not reflective of the price ratio.
