The problem is blizzard announced that pvp, m+, and raiding are all different means of progression.
PvP gets you 233 for all purchasable pieces timegated due to conquest cap, m+ gets one 226 RNG piece once a week, and mythic raids provide RNG drops of 226/233 for 10 bosses each week.
they are all meant to be viable routes of progression per blizzard, but m+ gets left behind both pvp and mythic raiding
