Event Points and Rewards.
Today I started doing the artifact enhancement for Karato fusion and noticed that the points seemed to be higher for the rare. I went back and compared old reward pages and sure enough, it costs way more points to get rewards.
Breakdown:
previously it cost roughly 3000 points to get the rare or the epic Book.
In this event the rare book is at 3000 points and the rare is at 3500.
In the shard event, the rare is at 2500 points and in the past at 2000.
There are no spares available for rares in tournoments this time, unlike in the past.
Even as a willing spender, the continued increase in cost of time and money required to continue playing will eventually suck the joy out of continued play.
Couple this with the constant increase in cost of packs for spending and I can't help but conclude that this game punishes you for both not spending and punishes you for spending.
