It's rough as a War without cash, but if you can find a server with a decent buffing population, you can prob get high enough quickly to farm for some cash.
Or do as I did on Tunare, and made a Shm first and got to 25 to make my own potions. Potions in bazaar are generally marked up 2-3 times the cost or more, with some exceptions, like gate potions are almost, if not the same as the cost with failure rates.
Doing Blacksmithing while you level, and the Tradeskill quests for the cultural armor patterns and augs, will help get you descent armor and for cheap, plus another skill.
Also, if smithing is not your thing ... Doing the Crescent Reach (if you have the Serpent's Spine expansion, 20 level armor quests (and most likely if you find a good guild someone will already have some patterns and pieces banked, so you just have to do the turn ins). You can find these quests from
Kimem Saydel.
You can also get various levels of Defiant gear as you level up, but it often drops off of mobs at the high end of the recommended level of the gear, but it is great gear, and even a tier lower is still great, and better than the cultured in general, and definitely bette than any group-level quested gear from TSS expansion at the same level.
If you haven't already, read the stickied thread on new / returning players, it covers alot of good information .. and for similar stuff as what I just posted, go back several pages, and look at the appropriate threads for starting out advice, gearing up, and making platinum in the current game.
