just got to lvl 70Follow

ok well im an arms warrior, use 2h axes which i know now suck in pvp.
im completly overwhelmed at what to do first, pvp instance rep whatever.
i need some tips from warrior masters.

Four things you can start with;

Arena:
Start this as soon as possible. The S4 gloves which will be a huge upgrade for you can be obtained with 3/4 weeks for only doing 10 matches a week (1.5 hours tops)

Battle Ground's:
Grind some honor in the BG's and start picking up easy purples that will grant your gear to do well in most 5 man heroics.

Heroics:
5 man instances set to "Heroics" will grant you a badge for each boss kill. You can then trade these for great instance gear from the quartermasters.

Gold:
Start doing dailies. You need the gold to enchant and gem your epics once you get them. You can easily do about 20 dailies within 2 hours for approx 200 gold a day with the right run.

You can do all these in parallel. There is no order.
