A ranger's int really only affects poison anymore, so it's not that big a deal at this point. Everything else (aside from offense stance using str) is a fixed damage value that is only altered by base spell damage.
Well I am still using seb croak on off hand. Just got the shield last night so until live won't change it out. The seb dagger gives the caustic bonus, the shield dps increas. I was just wanting to have more int to help with the poison proc. Don't need some much agility right? I would rather have the str 54 agi 32.
