I did a search and couldn’t see this anywhere in the suggestions forum.
From looking at the Guild Commendation Trader and the Laurel Merchants I can see that a Guild Commendation seems to have a value of about 2.5 Laurels so why not remove the Ascended items and all the boxes of class Gear (i.e. the Warrior Gear, Ranger Gear and so on) from the Guild Commendation Trader and allow us to just buy 5 Laurels for 2 Guild Commendations?
This would cut down on the duplication of items between the two and allow us a source of Laurels outside of the dailies and monthlies.
(PS I do know that the Ascended accessories are actually cheaper if you buy them from the Guild Commendations Trader but the price from the Laurel Merchants could be altered to compensate for that.)
