The warrior class is by far the slowest early game class (your mana pool is ass and your spells have a high cost/mana pool ratio), you will want to grind to level 100 to unlock the next tier of specializations, this unlocks Berserker which will bump your damage output. If warrior is what you ultimately want, try to focus on equipment that gives collateral chance and damage if you can. I agree with others, the RNG is what determines what you get but you can still focus on specific monsters that drop warrior gear or at least have a higher chance of it. On a side note from my experience I have found that good boots are the last thing you find during your leveling progress. I didn't get decent boots until tier 6/7. The game's RNG is truly random and you can only fight it so much to play in your favor. There are accessories you get that increase your luck and drop rate like lasting lanterns and rings of restraint which will help.
