My warrior dual wields Icebreaker enchant and this is the best dps'ing enchant for a whirlwinding warrior. The enchant responds to raid buffs so I get bonus's from magic damage and it crits for around 530 damage per weapon. I am getting Zero's for this enchant and would like it added to the 15 column.
I'm afraid none of warrior spreadsheets mentions Icebreaker as one of the best enchants for fury warriors. We'll investigate this further, but I doubt it will get score of 15. However, it should be higher than 0 of course, thanks for reporting it.
