Ok, If I'm being sensible I'd have to go *slap*...Pull yourself together! E/W is a horrible combination and should never be considered! You're squishy etc.. etc.. etc..
About the only thing E/W combination had going for it is [skill]"You're All Alone!"[/skill]+[skill]Stoning[/skill]+[skill]Glowstone[/skill]
However...if you're only wanting to do it for fun, and not planning on joining PuGs and really annoy your team's monks...I once tried an E/A build which has horrible energy management.
[skill]Glyph of Lesser Energy[/skill][skill]Ride the Lightning[/skill][skill]Frozen Burst[/skill][skill]Lightning Touch[/skill][skill]Death's Retreat[/skill][skill]Arc Lightning[/skill][skill]Lightning Strike[/skill][Optional Slot]
Basically use in order... GoLE > Ride the Lightning to target foe (best if there are a few foes in a cluster) > hit them with Frozen Burst followed by Lightning Touchm get out with Death's Retreat (or Return, if you don't have Nightfall), then spam Arc and Strike afterwards. Optional slot can be filled with a res, or air attunement, or maybe caltrops.
Please note: the build I gave above is
Crap, with a very large, emboldened, capital C....but if you want fun for 5 mins...
I mean, you could always go for the predictable, boring Confure + Elemental Weapon routine...
