Elec/Invul, curious about effectiveness/ect.

So, I've not posted much here, though I figure now's as good a time as any to ask for a bit of advice. I've a new concept I'm working on, Elec/Invul, and I'm simply wondering how well it'll perform in general. I don't think I've seen any around on my home server, so I'm not sure in general if many have tried it.

A build would be nice, but it's not needed. I've never run either set very high, so just some outlines on what to expect would be nice.

I'd expect it to perform very nicely if you get some IO sets to improve typed Defense, Endurance management and Recharge. As a long time player of an /Inv scrapper (since I3 or whatever it was at EU launch) who has a completely blinged out Kat/Inv I can tell you Invuln gets just stupidly powerful with good IO investment.

As for Elec Melee, mine is currently level 33 but I just love it. It has insane AoE which goes well with Invuln because you get more powerful the more enemies you have around you.

The only thing I can see going wrong with this combination is Endurance costs, but I think getting Stamina, Conserve Power and Physical Perfection should see you through it without much additional IOing to cover your Endurance bar.

You could consider something like this for the build. Not a particularly expensive one;

Great AoE damage and aggro control, great survivability against S/L damage, good survivability against F/C/E/N, less than average ST damage and toxic survivability, poor survivability against Psi.

It could be argued this is a relatively late-blooming combo, with Invincibility and LRod opening up at 28 and 32, respectively.
