For those considering pvp I will say this
Pvp is the fastest way to gear in wow. If you are a healer and are decent at all, you're able to control the wins with randoms a little better and gear faster.
If you get a fresh 120 and just start queing 3s with randoms, you will not only get geared super fast from the loot in each chest for a win(2 chests per win usually), but you'll also get base 340s randomly from wins as well(at even 0 rating, and the random drops seem to come fastest in the 0-1200 rating bracket). Winning 2s or 3s PVP matches is the absolute fastest way to gear a character to 340+ in the game. Higher chance to win in 3s, if you get lucky with two good partners. START your OWN group for 3v3 and title it like "3s to cap conquest". Accept high ilvl people and pray they are decent. Go for easy comps like healer, warrior, demon Hunter. Teams that just rush down healers for fast wins or fast loss. Don't try to do teams that require voice chat kill setups like priest mage rogue. Just go for beat down comps. Hell you could even get good wins with 3 DPS just blasting down a healer as soon as the gates open.
At 1400+ rating you'll be getting higher base items randomly drop from wins, higher at 1600, 1800, 2100. Also your weekly pvp chest reward will be an ilvl based on your rating assuming you cap conquest the previous week. This far in to the expansion, you'll get half your gear free 355s from conquest cap rewards that are all available for each week since the beginning. You can cap like 7 conquest bars currently for 7 355 items. By the time you get those 7, trust me you'll have full gear from random win drops including Titan forged shit likely at 370+
I usually hit 120 with 260ish ilvl from leveling 100% in BGs 110-120. Immediately queue for 3v3 arena with randoms and Bam the first win gives like a 340 and a 325, and you're off to the races!
