Since, Expansion is coming, Level Cap will be raised to 36.
It means we have to get new gears.
Im wandering, what if we compare the Level 36 Legendary Helm to a Level 26 Mythic Helm,
I think the Level 36 would be better.

So, Im suggesting that,
They should upgrade the Levels of Mythics, Because other people dont like to spend 3M + for a mythic gear
and then the level cap will be raised. They will feel bad about the Mythic because Legendary New gears are better.

Simply:

Upgrade the levels of all mythics for who has those things.

Just a suggestion

thanks for hearing out.
