Leveling up my draenei hunter, I used to keep looking for the next upgraded item I'd be able to use. My most exciting upgrading moment so far came when I reached level 40 and got to put on a full mail set I had bought and put away in the bank just for that moment.
Somehow, though, I wasn't able to find many upgrades in my forties, and now starting on my fifties, some of that armor I had saved in the bank is still the best I can find, on the auction or in quests. The surprising thing is that leveling still isn't that hard! Of course maybe it's just because I'm a hunter, and hunters can even level naked if they want to.
Still, it makes me wonder just how often we need to try and upgrade our armor leveling up. Is it totally different for the various classes? For example, can a hunter get by with sub-par gear for a long time, while a priest or warrior never could? If you're trying to level a very gear dependent class and just can't seem to find good upgrades, how do you manage?
