In I7 it will be even more effective if you take Power build up from the epics as this will now boost the endurance drain on transferance (and all other end draining attacks). 
Also it's being adjusted so you drain a %age of end instead of a fixed value.

Yes its still effective, at the moment I have electric mastery which has another end drain power which is an AoE, so it might be better for PvE. Short Circuit just needs to be spammed pre level 41 otherwise. Best done with a good tank around.
I use Transferance on the bosses or anyone refusing to drain. Keep using short circuit after they are drained too, or they will regen.
I've found sapping works really well with a Controller on the team too. Basically they get the initial lock-down on and from that point on you can keep them endurance drained and helpless. Otherwise you are looking at miffed mobs with a bit of Endurance left after the first SC (this is all pre-26 by the way), but hopefully you can heal yourself out any trouble that arises. The siphons of kinetics are wonderful slapped on lieuts / bosses too, especially at the moment as bosses aren't affected as strongly by Endurance Drains. This will be fixed in i7.
I've also found Air Superiority a great help as a soft control for a sapper. Combined with Hasten & Siphon Speed you can keep a boss off his feet while SC recharges.

Ok, with ED is it still possible to get this to work as an effective endurance sapper in PvE? All the guides I can find are pre-ED and suggest 6 slotting short circuit for end drain. Obviously that can't be done now.
If it is still possible, which powers should be slotted for end drain?
Thanks in advance
