Why I'm Liking My Bird Less and Less

[adwin]

Well, I have a similar problem to the OP.
I'm a lvl 39, 80% dex 20% str bird (have to respec), and it's nearly useless in AO/higher.
I'm wearing the best gear I could get for that level, but it's not really helping. Any tips would be appreciated.

Sniper's Scorpion Helm [pink]
Shivering Frozen Bow [pink]
Scorpion Leather of Finesse [purple]

btw, does ATTACK stat influence damage?
