I know this is the controller forums, but I have a lvl 50 Elec/Earth Dom that is a melee monster. If you aren't too thrilled with the controller secondaries (i would suggest /Rad or /TA as well), you could always go for a Dominator. /Earth fits with Elec/ very well as many of the powers from both sets work very well in melee and when it comes to single target attacks, /Earth can really put the smack down. I imagine that /Elec, /Icy, and /Psi Doms would also mesh pretty well, though that's more of an educated guess.
