Just a couple thoughts..
I found that I was quite annoyed with having to be on foot with a GD as Cerveza mentioned above. So I took my Archer/Tamer Gargoyle, trained up throwing, and it's absolutely a phenomenal toon to play.
Not only do you get to move at mounted speed with your dragon, there are a couple other huge benefits to going with throwing.
1. Throwing 120 scrolls are DIRT cheap.
2. No need to carry ammo!! Saves a lot of room in your pack for other goodies... Loot.. Pots.. etc..
3. Throwing weapons are one handed!! No need to waste a property on balancing a bow if you are a pot chugger.
-If you aren't a chugger, now you can be.
4. Soul Glaives rock, and hit like a truck.
In all reality, the only true drawback that I have come across is not being able to tame a cu sidhe anymore. But I'm well past my days of farming Cu's in hopes of getting a blaze one, so no real loss there for me.
