1. It'd most likely end up a toggle.
2. we already have a speed tree AA.
3. IT IS BENEFICIAL TO SWITCH IN CLOSE RANGE that just makes sense man... Shooting at something right in your freaken face with a bow no less is just ridiculous.
4. You wouldn't be forced to switch and the attack speed debuff might not even exist they could simply give u large damage boosts but total lack of alacrity from the tree.
5. The damage buff could also be solved by giving them mobility while using archers focus and allowing for larger increases in ranged power compared to the other faster firing tree.
6. Not everyone wants a speed shooter for their dps needs to be more viable slow powerful hitting characters just because you don't like it doesn't mean its not good for someone else.
7. Really? You don't want viable melee and range on a ranger assassin style tree? Being able to shift your fighting style to work on multiple fronts is in fact utility couple that with the decent healing you can pull outta this tree. Enough spell power and you can do a lot more than if you had to focus solely on speed shooting.
8. It is adding flavor but if the tree is built properly it will be viable flavor and any kinda flavor would be good for this game at this point...
Edit: It would be nice to drop in some extra crit ability or amplify the effectiveness of some of the skills that don't quite match up.
