We have always used the battlegrounds for the source of our initial EPIC items
Needless to say they are very important for our new LVL70 toons
Here are a couple of suggestions on spending your hard earned HONOR POINTS
If you plan on going all PVE/PVP
1. Get your Vindicators 1st!
2. Get your Weapon of Choice
3. Get your Glad Armor Set
Why in that order?
Vindicator items - expensive to purchase but its usefullness will last you a long time (even if they hand the S2 set by the next patch Vindicators will still be the best PVP gears that can be bought for honor) So its a good investment. IMO Have them chanted/socketed right away
You can use them for PVP/PVE without fear of loosing out on something(DPS,HEALING) until you get your PVE epics
Glad Weapons - These babies are really well worth it they are comparable to the KZ/Heroics Weapon drop which can really give your toon a big boost in either DPS or Healing and as soon as you get them pls have them chanted its not a waste on G
Glad Armor Set - We cant argue the Fact that they are good armors, But they are specially made for PVP/ARENA/BG which can easily be replaced by epics that can be looted at world instances and raids. The armors are good but i doubt that you would like to spend all your days in PVP without experiencing the world... and as much as i like them (used them for my initial heroic tanking gears) i'd prefer purchasing the 2 above before the armors
P.S. There are rumors floating around saying that S2 gears will be available on the upcoming next patch
If you plan to go PVP all the way
1. Vindicators
2. Glad armor set
3. Glad Weapons
Cheers!!
