Yurneroo's fish guide is still good. There really aren't any significant changes to any build in fish, you only add heroic power and the new attack skill. Granted, str fish are obsolete these days, skills are 99.9% the same if you're vit. Only thing different is if you're vit knight you should max blood effect instead of lunacy and maybe mist for it's entertainment sneak attack factor. Sage is all same just add wide ffs ;D
