Hello EJ!
Me and two friends decided to start up a 3v3 arena team going with a holy paladin, arms warrior and discipline priest. We havent played together in any arena before, so we're far from perfectly synched.
Started early S4, alright gear I guess and from each of us having played 2v2 around 1850 rating we got some kind of hang of pvp.

Got a few questions though: It seems with our setup we're very vulnerable to 3dps teams. They either take out me or the warrior really fast while CCing the paladin. The same goes for 2dps / 1 healer teams.
Especially rogue/rogue/druid it just seems impossible to get away from the rogues and we're kinda fumbling around in the dark trying to figure out what we can do against it, or the warrior/retri paladin/resto shaman teams. Granted S4 just started and the guys we're facing seem awfully well geared compared to us aswell as very synched.
War/pal always aim for me(pri) and I just cant get away from them as they spread out and eventually corner me. BoF hits and I burn a fear in hope to get around a corner and get away. Also our warrior is having issues taking down their healer before I'm gibbed by their insane burst.
I've been considering rolling engineering for the rocket boots, and I reason like this: What good will the sta/mana and healing that I'll miss out on, do to me if I die? Might I have gotten away from them if I had the boots?
Our warrior's also tried slowing the pala/war down with hamstrings etc to buy me time to get away, maybe we should start focusing on the paladin straight off? I cant really burn against that setup since if I'm caught I'm dead.

We've faced other 2 healer / 1 dps teams, and those havent been a huge concern to us, but we have yet to see a mirror team, are there none out there?
Any advice would be awesome!
Thanks
