Spears are perhaps the fastest way to level up a ranger, and that is why they are becoming so popular. If your using a bow, you most likely have some points in Rapid shot, bolas, steady aim, sharp shot, light heal or bandages, or rejuv, and med. Using a Spear for leveling, you can dump points into basically three things, Rapid shop, light heal, and Meditation. This allows you at even fairly low levels to have almost maxed skills. Also with a spear you can equip bucklers and shields allowing for a nice boost to AC. My Ranger with a spear is farming mobs 10 levels higher than he is. I said farming, not soloing one, and taking 3 min to heal, meditate, etc.. I mean one after the other with little downtime. There is nothing wrong with either the bow or the spear, they just allow rangers to have flexibility in play style. I know when alot of folks think of a "ranger" they get this image of Robin hood with a long bow, but I tend to think of the German Celt type of hunter that used spears to hunt wild boar and deer. I used to live in Germany and seen the spears used by the celts, romans, etc.. in museums, so Its just something that I grew up with.
Ummm meditation wtf are you useing that for?
