I assume you're quite low levelled if you're relying on AH gear. Since warriors are the most gear dependant spec, small changes in stats make a significant difference to your damage output. I would recommend upgrading at the AH as often as you can if you're grinding your way to higher levels. Run instances where possible to get better quality drops.

No point spending so much money if you don't have a rich main to sponsor your warrior especially if you're not planning to stay long in a particular level range.

Again, with all the effort taken to get pvp rewards, even the vendor ones, can you really say it's worth spending all the time pvping to get gear that will be replaced in 3-4 hours worth of experience point grinding?

Comments don't apply if you're planning to stay at a certain level range for twink pvp.

have to disagree there.. AH greens are usually better than the green quest items you get from levelling 1-60. And if you're just power levelling, "of the bear" and "of the tiger" gear are generally cheap upgrades and help provide significant boosts to your dps and helps you keep up your xp/hour.

There are a couple of landmark items which you should get from quests though which will last a long time.. Whirlwind axe from level 30 warrior quest, Sword of Serenity+1 hander from RFC is a good DW combo available from lvl 39, thrash blade from maraudon which is nice and slow at about lvl 49 from Maraudon. Can't think of any others that come to mind atm though :/

Anyway, I guess different people here have different takes on buying the cheap stuff from the AH. It's up to you which advise you follow and whether you want to slowly experience classic wow at your own pace or power level to 70.

If you're powerlevelling, nothing hurts more than trying to do it while you're undergeared for your level as a warrior.
