My Fire/Fire Scrapper. Comments? Suggestions?

So here's the deal.. I've got a fire scrapper that I pretty much love right now. He's got great offense and sufficient defense.

My dilemma is this: I HATE the swords and avoid them at all costs.. and i LOVE Burn and want to use it religiously. The only way to work around the high fear effect it has is to slow/immob my enemies from an Epic Pool.

My thought is to take Weapon Mastery for Caltrops and Web Grenade.. or Dark Mastery for Ten. Tentacles.

My attack chain would look something like this:
Jump in.. toss out Caltrops, Build Up, Burn, Webnade (bosses/LTs), Single Target Attacks, Fiery Embrace, Burn, Single Target Attacks.. all with Blazing Aura going. Rinse and repeat.

I am thinking it would be best to go for Caltrops because it doesn't require much (if any, maybe a couple slows) slotting, as opposed to Ten. Tentacles.

Am I gimping myself by foregoing the swords? Or is my AoE DMG more than compensating?

Thanks for any and all input!

I would go with the swords. their combined damage is very high. Your idea of caltrops could work well, but as they will try to run away from the caltrops (slowly) when you throw burn they will not want to stick around, thus negating any taunt effects of blazing aura. I personaly hate when mobs split up.
