Fire/WP Brute vs. Scrapper (Pros and Cons)

Hi all! Thought I'd run a quick question by the many minds on this board. If I'm going to make a Fire/WP, what are the pros and cons of Brute vs. Scrapper? (No offense, but right now I'm not looking to make a Tanker )

I was thinking Brute:

-Higher HP
-DoT gets boosted by Fury
-Gloom
-Superior Conditioning > Conserve Power (at least for my purposes)
-Incinerate at level 8

But I'm sure Scrappers have some advantages too:

-No Fury, no problem!
-Fire Sword Circle at level 18

One of my main Brute pros is that the optimal dps chain for Scrappers is

Incinerate > Cremate > GFS

which requires quite a bit of recharge in GFS (more than 200%)

while Brutes can run

Incinerate > Gloom > Cremate > GFS

for HIGHER dps with only about 50% global recharge, OR

Incinerate > Gloom > GFS

for EVEN HIGHER dps but crazy recharge.

I know there must be reasons to make this toon a scrapper instead, but I need some supporting details. Anyone have more Pros and Cons for either choice?

Oh and P.S., would this combo come highly recommended? I love both sets and I am familiar with their strengths and weaknesses, but I'm just curious what kind of performance you can squeeze out of this combo. Any fans, I welcome your input. Any detractors, I welcome your criticisms.
