I'm actually not familiar with PvP, especially arena seasons. Can you clarify what it should be, and link to enough evidence that I can correct this?
As far as I've looked up myself, it had a rating at some point, and then when the next arena season hit, the rating went away.
Actually i've looked at the vendor and according to this post it is suposed to have 1850 rating requirement for all the season 3 Weapons and 2000 for the shoulders and the vendor have 1800 rating requirement for weapons and 1950 for shoulders but the problem is not really the amount of rating requirement (1950/2000 ) .. it is that people can just buy that axe without any rating requirement (exploit)
But theres no rating requirement on the item so of course they can buy it without it... thats why its important... right?
