Icefang is completely worthless in high reaper.
Sure. But... who talk about icefang? We talk about Alchemical Attunements. And it's simple: Earth >>Water>> Air/Fire. It's why majority players use Meltfang on primary Dino weapon, if they use Dino weapon. And for off-hand, if you use off-hand Dino/Alchemical, second BiS is Water (exclude Arty, they use DwM runearm).
It's something like 15 points of damage.
Cool. 15 >>0. So?
Look, you can remove the augments so go try these out for yourself in R10 and come back and tell me how much you like it. If you haven't experienced it before you are going to be stunned at how much it is affected.
What augments? Sorry, english not native for me, i just don't understand what you wanna say.
Believe or not, you're not single player who run R10. And majority, include Ying (and me, lol), use Meltfang, not Flamefang for primary weaponz. For off-hand is wide choice effects, i personally use Water attunement from my Alchemical SSword just because it's secondary BiS DD effect for my non-caster toons. Again, it's simple. 8)
And your suggestion use Flamefang instead Meltfang... it's just harmful advice.
