For the most part. I can see how this would be great with friends. Solo, its alright, the fact that I cannot take on more than one enemy at a time is annoying but not totally unexpected as a low level warrior. Do warriors get projectiles? Magic, guns or otherwise?
Warriors, for the most part, are a melee close combat class. You tank with a shield and 1 handed weapon at melee range, or you DPS with a 2 handed weapon, or two 1 handed weapons melee range. And, once you hit level 60, you can spec deep Fury to get Titans Grip, which lets you equip two 2 handed weapons at the same time.
You can use guns, bows, and crossbows, but those are really only used for stat sticks as a Warrior. A stat stick is just a slot that you equip that gives you beneficial stats from the item. Such as a gun or bow having +agility and attack power on it. You can use the ranged weapons, but it's not on a auto-shoot function like hunters, so you have to constantly hit "shoot" for it to fire, and at melee range you cannot use ranged weapons.
You get Heroic Throw, which is a higher level ability that throws your weapon (not permanently obviously) at the enemy causing high threat, and doing moderate damage.
Warriors also get shouts. Challenging Shout, which focuses all enemies to attack you. Demoralizing Shout, which reduces the attack power of all enemies around you. Commanding Shout, which increases your total HP, along with your raid/party members, for a short amount of time. And Battle Shout, which increases your attack power, along with your raid/party members, for a short amount of time.
All in all however, it's a melee only class. You have different charge abilities, or gap closers, to get closer to enemies though.
