I just realized something: warriors go with any secondary...
monk: obvious choice, healing your basic meatshield or dealing holy damage with smiting, or becoming invincible with protection.
necromancer:raise an army of fellow tanks, heal your wounds while dishing out more damage, or debilitating your enemies before moving in for the kill.
mesmer:not an obvious choice, but can tank with domination, has great evasive moves with illusion, and inspiration is great for energy driven warriors.
elementalist:while energy can be a problem, fire works well at long range, where warriors are weak; wind is better for spiking single enemies, but gets the job done; earth is like tactics or protection prayers, and water works like curses.
ranger:fight witha fellow animal tank, long/close range with marksmanship, and healing and traps with wilderness survival.
Well, there you have it. Sorry for the long post, but I've proven my point :D feel free to comment, but please don't flame other peoples opinions.
