I assume that there isn't a 100% perfect answer but in your mind what would come close to the best possible compromise between these two groups?
In my mind the best option would be to cap power obtained outside of progression systems to roughly normal/heroic while removing all/most long term progression systems from the game. As for long term progression I could see a mythic/elite recolor being available though a long term grind would be better reward.
What are your thoughts on it?
