Back in the day you could gear up with honor gear via bgs and while not the best gear it would be competent.
You could gear up with an honor set of gear over the weekend if you put the time in. Nowadays the honor gear available at the vendor is garbage. My main Havoc Dh has an ilvl of 100 and I still get stomped by players with +120 ilvl gear. The ilvl for the honor pvp vendor gear is only 68 which is utter garbage.
Why even bother with it when you can get better gear by going out and doing the daily world quests? It’s not the players fault for wanting to play in bgs but not having an adequate way of obtaining said pvp gear that is meaningful in there preferred way to play (pvp).
