Remove Af 1.5 from the vendors and all the fending gear from the vendors etc etc, then they can drop the myth cap.

AF 1.5 gear should be token drops from the hardest content in the game. E.g. Drop a token on HM Titan, Turn1, Turn2, Turn4, and Turn 5.

AF 2 should be a token from Extreme Ifrit, Turn 6, 7, 8, 9..... etc

The tokens should be RNG based and drop randomly each week so no one gets their crap in one shot unless they got really lucky.

The cap exists to allow people to get gear, not prevent them from getting it.
