Fire rogue for fire sorc?

So, I'm too lazy and too emotionally attached to the Ice rogue after 90+ levels together to try another crazy theory..

If I run a fire sorc the

Enchant effect is kinda wasted on the frozen

Arrows.. So why not use fire rogue with like

Blood Raven's Charge or Phoenix?

Bonus from

Enchant is moderate (~700 dmg).. Will it be further reduced for ranged attacks or will it be full when added to an explosive arrow?

And sunder won't apply to merc, right?

I remember watching some guide with a strong fire rogue, but the guy had many more points invested into

Enchant and

Warmth there..

And still can it be somehow beneficial compared to the Ice and its crowd control effects?

PS I know that the best merc is Emilio with Infinity, but still stick to rogues..
