I would just like to raise the question about this, I've talked to a lot of people and even though it's 'only' regarding cosmetics it's something that bothers the community.
To access the transmorgable elite pvp sets one needs 2k achi in 3v3/5v5/RBGs, this is all fine, a bit lower than 2,2k that it used to be. You also need 27.000 total earned conquest points in the season, and on top of that they cost as much as the regular pieces (3500 for weapons, 2250 head etc).
The concerns are that the price per piece is abit much, some classes have 2 or even 3 speccs to gear up, or alts to play. 27.000 is also a lot of total earned and takes some time to gather, at about 1750 (should be the average player) you get 2k per week.
That's slightly over 13 weeks of caping, and not missing a week so it might be troublesome on alts. It won't grant you full set with those points either, so back to grinding, aaaand there comes the end of the season.
