I don't use PVP, Purple, or AT IOs in my builds... Have no clue how available they will be even months into relaunch so I figure it best to work a build without them.
I loathe breath of fire... way too long activation, low damage, and tiny arc.
With my fire brute (It was Elect/Fire/Fire) I used it for teaming and farming which is why I got my melee defense so high...otherwise splat lol.
I rarely used purples unless it was something like my earth/psi/psi dom where I truly wanted a huge amount of recharge. Looking at our builds even with your focus on recharge... your attacks are on average available 1 to 1.4 seconds faster. If accuracy is something you worry about the kismet proc comes in handy if you can spare a slot.
I also like to stealth proc + SS so I can ghost things if need be (Especially when trying to get Hero merits etc... very helpful to be able to go as quickly as possible).
Just some things for you to think about, but ultimately whichever build fits YOUR playstyle is the one that is best for you

This is what I have come up with, the Melee Def isn't as high, but a couple of Def Insp will cap out Melee/Smashing & Lethal Def. My Dam, Acc, +ToHit are higher though.
