Don't go with IDF unless you plan to have a lot of minions. I would suggest getting a regular form like enrage instead.
As for electrical powers that work with the Heavy Weapon set, you should consider Sparkstorm with the Electric Personality advantage. It will let you keep this running in the background while you smack things around with your big sword. It also has the advantage of helping you build rage stacks. You can even add challenging strikes to it if you want to do some tanking.
Also, skip presence and get something to help you with your energy instead. Which stat you get depends mostly on which energy unluck you chose, which in turn depends largely on which actual attack powers you plan to pick.
