Fire/Fire - Bonfire vs Fire Breath

I know, the subject may seem crazy, but I'm seriously looking for opinions here.

Here's the thing : I took fire breath on my Fire/Fire dom as soon as I got access to it. It was my first real AoE, and it was Good®. But now that I have Fire Cages, Consume, Hot Feet, Flashfire and Combustion... Well, I find it a pain to jump out of melee to maximise FB's targetting. I'm pretty sure it hurts my damage output overall.

So, since I use Fire Cages anyway, I was wondering about switching FB to Bonfire, since FC would cancel its KB... I know its damage is much slower, but since most my Fire's powers use DoT, it would still fit. Plus, it hits a max of 16 targets over a 50' circle instead of 10 over a narrow cone...

So, what I'm interested in, is feedback. Who uses Bonfire, and who can give me info and/or opinions on using it regularly? your help is, as ever, much appreciated.

That is a somewhat viable approach with some caveats:

1. Fire Cages uses tons of endurance, unless you are running Cardiac or have lots of endurance reductions slotted you will have major endurance issues.
2. The -knockback time on Fire Cages is 12 seconds and is not enhanceable as far as I know -- maybe something like secondary effect boosters might affect it, but I don't really know. It will need to be refreshed often.
3. Fire Cages has low accuracy so make sure you have enough accuracy (global or slotted) .
4. Bonfire does it's damage over time and pretty slowly.

I'd definitely get Combustion first and use it as an AoE power in preference to Fire Breath and Bonfire. I like Bonfire for a bit of extra control in some special cases, but as a damage power it needs a lot of attention and excessive endurance to use to good effect. Fire Breath I'm not such a huge fan of, you need to spend lots of time positioning while wasting endurance and damage from Hot Feet (assuming you are running it). I do play high defense builds though. If you play mostly at range, then Fire Breath is pretty important.

Bonfire is particularly good when you can corner or wall mobs and get nearly perma knockdown and decent damage without having to worry about Fire Cages.

Bonfire pisses people off, Fire breath does not.
Don't be that guy who throws bonfire on the doors in BAF.

12 seconds? Damn, that's short. The corner option sounds doable though, since I used to Wormhole and Herdicane stuff all the time. I like that Bonfire has more utility than FB. Sounds like a good power to have to avoid a team wipe.
