In the battlegrounds, you’ll often find yourself pit against a group of enemies (hopefully alongside a group of allies…if you’re off by yourself somewhere against a full group of opponents you’re probably in the wrong place). Scanning over them you can make out the various classes and races…”lesee, a mage there, hunter over there…no rogues, but that’s not to say they’re not there”…generally by examining prominent pieces of gear. This is why the shoulder items from the arena have the highest rating requirement…Blizzard decided that you should be able to glance at someone and think, “I know that person is high-rated.”
However, this tells you something. You know things about your opponents by examining their armor. Which brings me to my point:
If I see a priest in Primal Mooncloth, or a mage in Spellfire, or a warlock in Frozen Shadowweave, they become priority #1 as a kill target.
These sets all have very little stamina at best, and zero resilience. Their wearers will drop quickly, even with heal support. Especially with healing debuffs in place. The same goes for rogues and hunters in quest greens, as made obvious usually by bright yellow or green colors and exposed toes on the boots.
It’s the shoulders that make them obvious, but sometimes lending to that are helms, depending on whether or not the graphic is enabled.
Regardless, everyone, no matter how recently it was you hit 70, should buy the level 70 blue pvp gear from the various rep vendors. This will give you a base-line 100 resilience or so to start with rather than being (rather useless, sometimes) fodder for the other team and a waste of mana for your team’s healers.
Also, when considering gear upgrades for pvp after hitting 70 and obtaining said gear, weigh heavily items that would increase your stamina the most. If you have any items with 0 stamina, get those replaced first. This applies heavily to caster wands and jewelry obtained from quests, which often give less consideration to stamina than other pieces of gear would.
Also, until you have a decent amount of resilience on your gear, gear heavily in the direction of stamina and resilience. As a dps clothie, your best bets are probably all Glowing Nightseye and Steady Talasite, matching socket colors to maximize itemization and overall character potency in addition to obtaining some survivability. Taking into account the fact that talasites are freakin dirt cheap (at least on Skywall…<10g per), it’s not a terribly expensive way to gem up either.
In short, please don’t come into the BGs with less than 8k hp…seriously…
