Warriors are one of the key raiding classes, but you might not be welcomed as a tank until you hit 60.
To do the best DPS you need to be berserk and use the precision disc, but this is not going to happen if you are on the tank list. Even if you dodge the tank list you may not be able to berserk due to AoE damage.
I disagree that you need to put too much resources in to a warrior. Trochillic's Skean is generally free, and is a decent aggro weapon. For primary try get your SK or Ranger on board with some WW dragon hunting (such as talisman farming) in order to quest a Frostbringer. Frostbringer/skean will take you to 60 easily.
For other gear, crafted armour (as in the stuff quested in South Karana) is easy to obtain, and I wore it well into my 50s with no complaints. Once in the 50s try to get groups going in Velks and you'll slowly acquire Crystal Chitin, which is decent enough. You'll also come into Cobalt armour levelling in Karnor's Castle and Old Seb too.
For haste, warriors get a decent entry level haste from Plane of Sky (Belt of Concordance), which is basically rot tier.
Before you are planar enabled, hang out with your sk or ranger in Velks. Often level 60s will be farming items, and won't mind you hanging out with them to absorb the xp they don't need. The SCHW that drop there are lore, so you may be able to get the loot rights to them cheaply on site, or even free on rot!
When I was soloing my ranger on frenzied broodling I was suprised by how many pairs of schw I ended up giving away.
Good luck on your quest, my first toon was a SK too, only got him to level 51. I then switched to warrior, then ranger and now play my warrior again.
Both warrior and ranger are fun raid toons
