Was wandering... is Zen Archery that useful? i mean range is a secondary option (use mostly for burst) so not being centered should not be a big deal?
I ask cause you, almost, convince me to take range option... but since feats are tight, and i would love to fit in: Toughness and Epic Toughness (over a 100HP more) gotta make a choice.
So 2 feats to "chop": not a completionist so that's 1... still missing 1... and was thinking Zen Archery... unless you have a better option to propose.
