No kidding! For 20 seconds, a Ranger can put out just as much dps as a melee... then he/she needs to wait another 1:40 to be useful again. Imagine this for the melee types... you hit your "okay, I'm going to swing my sword for a bit" button, and you have 20 seconds to do so. Then, for whatever reason (your arms get tired, or whatever), you can only get one attack per second-and-a-half. Then, 1:40 later, you can melee full speed again. *sigh*
More ppl would play ranged-type char's, and it could be a TON of fun. Rangers focused on ranging... bow-using rogues with sneak attack... fighters who specialize in bows... barbarian "mongol" builds... changing manyshot to a stance could really bring a lot more depth to the game.
