Why is everyone saying such nasty things about the game and its developers, and threatening to quit over one bad reward season, yes it could have been way better I also read the rewards and thought, none of my characters would wear that and I don't want that in my stronghold. The problem isn't they don't want to give you a great reward, its just there're limited in what they can reward you with, by which I mean anything they give you they can't give everyone else which would be unfair depending on how game changing that item is. That means custom color crystals are out and anything that boosts stats in any way is out. That pretty much leaves custom armor, weapons, pets, mounts, furniture etc. Now the thought of re-usable pvp stims sounds workable in my head, the ones you buy with pvp comms, that would save the pvp winners a lot of their precious comms.
So to sum up, you can get any pve reward you want anytime, they can't get pvp rewards after all is said and done, so they do care they're just being fair.
