- There could be some build for DH or monk similar to Carnevil that turns a primary spell into a main damage spell.
- You might need to hit a breakpoint at some point and would kill for 7% IAS.
- If you're not only playing solo but also in groups, 4% more CHD would probably be the "biggest gain" if you desperately want to re-roll it now.
- 5% chance to freeze a lot? Equip Azurewrath+Frostburn and try to perma-freeze anything, and see what 25% freeze + 50% on gloves do. 5% freeze is a gimmick and offers no reliable crowd control at all.
=> Everything but keeping it as-is and waiting for what you really need in the future would be a huge mistake. As a general advice to anyone: please do not destroy good items by re-rolling them right away. As a rule of thumb, whenever I get a well-rolled item I don't touch it for at least a night. Even if it's obvious. A WH like this won't drop for you again (most likely), so there's no hurry at all.
