I've seen a lot of people saying how they only do BG's and think BG's need gear like Arena's. Allow me to explain some reasons I think they don't.
First off, think of what a BG counters, this would be normal instnaces. BG's give gear, but not as high quality gear as Arena's, just as Instances give gear, but not as high quality gear as raids. BG's are Like 5 man's in the sense that they are meant to introduce you into PVP and let you ahve some fun times without doing the more hardcore stuff.
Seconed, you ahve to think of the actual problems caused by this. By the end of BC most people got Merciless gear by going around and Afkin in a Battleground. If BG gear came out then this would see a Sharp rise because people would be getting gear, and not only not working, but not doing anything, making it harder on you. IT doens't matter to them if they win or lose, because they didn't invest any time. You might be thinking "They could invent some system needing kills for it" but where would that leave Healers? Inventing a System for that too would just let healers afk with some Macro/addon spamming spells for them. Other people like Tanks who do BG's (Say for AV or something) will not be able to get killing Blows for their stuff over the DPSers.
Third, work. As I stated before, BG's are Like Instances, easier things to introduce you into this stuff and so you can have fun (even raiders like to do BG's to have fun, and I assume even PVPers like to do some instances for fun). Arena's are more work and are harder and require more skill, and I don't want to hear someone saying "no they don't" because a BG has 9, 14, 39, (And the other numbers here, don't remember Strand/Eos
) covering for you or other people who have lack of skill, where as the Arena only has 1, 2, or 4 other people covering for you, and even then each one makes a big difference. The harder you work, the better stuff you get
Four, Current system. Just as new five man instances will come out, new BGers gear will come out. This BG gear will be old Arena gear (
if they do like they did in BC), while it's behind, you still get gear for doing Battlegrounds. You earn Honor and Marks (Granted right now the marks don't do much). If you don't wnat to do the more Hardcore stuff, you are going to have to wait for your gear =p.
I can understand some of your frustration, but if you think about it it's really Fair that the easier things give less gear. I'm not saying BG's are Easy or anything, but I'm saying they aren't as hardcore as Arenas, just as instances aren't as hardcore as Raids. The more Hardcore stuff you do, the more rewards you get =).
