haha grtz!

sounds exactly like my first 10 games! dinged 70 on a tuesday and wne to get my arena team, tho i didnt have the luck to get a healer so i brought my girlfriend on her lock won 1 of 10 with her standing alone vs 2 druids 1 balance and 1 feral...

tho i can tell for sure it will go better during every week since you prob will get some S1 gear and some random faction stuff =)

btw a tip for you is to bake in your dmg trinkets in your spells to get less buttons to keep a check of
IE
/assist focus
/cast trinket one
/cast trinket two
/cast chain lightning


this will make it so one trinket pops W/O delay when you cast and when the buff is off the 1st trinket the second one will cast the next time you hit the button.
this also works with elemental mastery and nature swiftness... i got them all in same macro to reduce buttons

good luck with your arena
