Per our previous discussion, I do believe typed defense is better option for resistance based sets. IMHO, you can obtain greater defense coverage with out sacrificing base values and game play for resistance sets.
That stated, the changes I've recommended here are based on the idea you want to keep all these powers. I'm tempted to suggest you drop a power pool and swap in Hasten for additional recharge, but that will require more changes to the build. something to think about for later as you'll have to decide what to drop. I also don't like RotP, but that's a personal preference and I did not want to change you're power selections.
Unfortunately, this will require the movement of several slots. I get where you made several choices in the pursuit of Melee defense. Again, you really can't mix typed and positional defense. It's either one or the either.
Obviously, this build could use further tweaking, but it does obtain 44% S/L defense and 41.2% E/Ne defense. Now remember, you still will not have defense debuff resistance, so some tactical adjustments will be required when fighting mobs that dispense defense debuffs like it was candy.
You'll have some defense to Toxic and Psionic as those are usually ranged attacks, but at 30% ranged defense, it's still a weakness to keep in mind...but then we can't all play Dark Armor

Arc #6015 - Coming Unglued
"A good n00b-sauce is based on a good n00b-roux." - The Masque
Posting my Dark/Fire brute here for comment. A few notes:
I like as much rech as possible, because as I have recently learned, Burn is something most CoX enemies REALLY don't like
I've been told that it would be good for me to get my Energy defense above 30%, but I can't really see how to do that at this point.
My current SL def shows 44.6%, and my Melee shows 50.8%, but energy only shows 17.1%...
Thanks for the help!
