I've specced my mage around shatter in the 29 bracket and I'm not finding it all that effective. I have 3/3 frostbite to make me freeze targets more often, but rarely get off my big frostbolts in the battlegrounds against frozen targets. I seem to be more effective with frost nova/arcane explosion to get crits, but that is almost a suicide act.
I'm not done gearing out my mage, but I'm really wondering if is viable at all in the 29 bracket. I'm not a twink, but I'll be leaving the mage at 29 so I have someone at the level to use to group with friends in the BGs.
Has anyone had success with shatter at 29? I find myself relying heavily on fire blast, cone of cold and arcane explosion to do most of my damage. Perhaps I need to respec to boost the shorter cast spells?
Thanks.
