%att vs %damage, for marksmans?

Which one is better? And what i really want know, and for marksmans? Makrsmans don't have much att so wouldn't be better %damage?

The amount of att you have is irrelevant to how effective %ATT is, so as long as you have at least 1 attack.

Marksman gain a lot of %TD (not all of them appear in your range) through their skills and assuming you have a few link skills related to %Boss and %TD, you should be focusing on %ATT. Your weapon potentials should be a good mixture of %ATT and %Boss.
