AS is so nice on stalkers now you can do decent damage even with EM. The baseline for any stalker primary is about 200 DPS, before incarnates. Intuitively, I'd guess something like EP BS EP AS BS ET BS AS might do OK. I haven't checked the numbers or anything, just a gut feeling.
EM is great for single target damage.
It's primary problem is speed and complete lack of AoE.
With the recent changes, it has improved immensely but it still suffers with long animation times on ET and TF.

EM should be pretty strong come i24. Procs in Total Focus and Energy Transfer should activate 90ish% of the time which would add 200ish damage to each attack if you slot 3 of them. Figure out a chain to get ET to consistently critical and you will be laughing. Bwahahaha!
I was thinking about making an energy melee/ice stalker for pure AV heavy hitting goodness but it seems like kinetic melee is really the better option to go with. I actually like the animations for energy melee's assassin's strike and energy transfer.
I'm not sure, however, how the energy melee ST damage is on a stalker compared to other sets. Am I wasting my time going with energy melee or are there players out there that still enjoy it even after the energy transfer nerf?
Also, the lack of an aoe attack might be a downer at times but I was planning on picking up waterspout or some other patron power to help with aoe.
