it's all come down to you to decide, everybody have different opinion; however, i don't really like the ice bow, i'm more of a light side. Basically people want to have ice is because they have the chance to stay survive longer, but if you want ice to tank then why play bower?, plus bow is all about support class, range attacker, not suppose to stand still and tank like blader and glaive, us bow need to use phantom

my build: 90 bow/fire/light 20 ice(just enough to get snow shield)
