Terrible for Brutes? I don't think so, but it depends one what's hitting you. It has a weakness to Negative energy, but in the 30's you can withstand rikti ship beams while invasions are going on.
anyway, as far as Stalkers go, /ElA would definitely help speed up BS/ a bit on the recharge, also BS/ is heavy on endurance so Power sink and energize would help with that. The only thing that irks me about it is that BS/ has Parry which helps out your defense, but /ElA is a resistance-based set. Other than that it looks good.
by EA I totally meant energy aura, electric armor is awesome and bad ***.
ooooOOOOoohhh, ok.
energy aura might actually work better since it's got more defense to work with Parry. Plus it's also got the same conserve power/endurance drain powers that /ElA has too.
/EnA has that repulse move too, good for a hasty escape if necessary.
EA for stalks is actually pretty decent. It's defense based, which is SIGNIFICANTLY better then Resistance based sets(Elec Arm is actually not that great for stalkers). You can easily cap your Lethal defense with Parry.
Repel is pretty meh, good for an *oh ***** power, but I wouldn't run it all the time.
Best part of EA is Energy Drain, which basically gives you infinite endurance. Oh, and Overload is prob the best Tier 9 power in the game.
Leveling up an /EA stalker, and so far so good. 
I recently created one too. I am heartened by the positive responses in this thread. Mine's still a baby so don't know how she'll mature yet, but the sets seem quite fun at low levels. And /EA is pretty. Got to be Strong and Pretty. 
How are these two sets in stalkers, I'm thinking of starting up a BS/EA stalker, but I know EA is considered pretty terrible for brutes, I wondered how it fared on stalkers. Same thing for BS, just wondering about how it runs for stalkers.
