I'm developing a concern about the balance in the results of Rift Battles, specifically at the Diamond 4 / Gold 1 cut-off. If you're in the top 1%, you're getting diamond keys, rift coins, and diamond shards. If you're in the top 2% though, you're only getting the rift coins in that set, and if you want diamond keys, you're probably going to be having to spend your rift coins on them.
What I see coming out of this though is that the top 1% and the top 2% are going to increasingly going to diverge, with the top 1% growing stronger at a much higher rate than the 2%. Since doing well in Rift Battles is largely dependent on the depth and strength of your roster, I'm not sure how these players in the top 2% will ever be able to catch up.
I admit that this is slightly a selfish concern, since I'm currently set as a Diamond 4, and I have a lot of Gold 1's around my score, so I could see myself falling off the ledge as it were at the end of the week, being ranked Gold 1, and then just basically being left behind forever. I mean, clearly it's not going to be quiet as bad as that after only one week, but every week where I'm not Diamond 4 is going to leave me slightly less able than other Diamond 4s to stay a Diamond 4.
I guess on the flip side, it would also feel weird to do well on average and it's increasingly obvious as I go on that Gold 1's are never really going to catch up to me.
