I find it annoying that they make Elite PvP sets a "one upon a life-time" to get, while Mythic gear is avaible to be farmed later.
Wish they just added the Elite gear back, but made it cost twice as much Honor Medals (or what ever they are called) as other PvP gear. Making it a bit rare, but possible to farm.
Or perhaps give us a chance to buy them at a vendor when/if we get the rating needed at a later date.
