matchmaking needs to be consistent for mythic players. ethereal diamonds for example will have rewards that are capped based on their level but still has to face mythic players so it's a bit unfair in that way.
rewards need to be restructured better to entice players to level up and keep their ranking before the start of the weekend battles.
Yea that is the whole point of this article. I think the pool of mythic players is smaller and that is why ethereal diamonds have to face mythic. But if the rewards were changed and mythic had much better rewards then people might actually want to play at the mythic level. Which in turn would make match making a little better. This is just a theory however. Would not know for sure until changes were actually made.
