recurve bow - why?

i think recurve is the one i mean.
i mean the one that takes forever to reach the target due to a huge arc made by the arrow.
my question is: why should i use this weapon when it is so easilly dodge-able and takes so long to hit?

you describe a FlatBow.

Why use FlatBow:?
- targets not moving or aggro-ed take the hit (great for pulling and initial Poisoning)
- arrow flight is long time, but recharge among fastest, so fires at the rate of a shortbow

I use a Poisonous Flatbow of Marksmanship (15%^50 health, Marks +1 @ 20%) with ApplyPoison (Oath Shot as my elite) to 'pull' that small mob. Why Marksmanship? 20% chance to add additional dmg when it takes that hit AND gets poisoned AND 15% extra dmg AND 20% extra dmg when customized = not a very bad Aggro Shot.

Basic Bow Principles:
Short/Half Moon = quickshot build
Flat/Long/Storm = pulling or from a safer distance
Composite/Recurve/Dead/Shadow = interuptor build
Horn/Ivory = purely for heavy melee armored mobs (warrior class), slow bow, heavy hit

Flatbows have the range of a longbow and the attack speed of a shortbow

tho the flight time is long... under RtW or Fav. Winds the Flatbow is the "best" bow

thanks guys.
this helps alot since im relatively new to the ranger class...
