At -.3 end/s, you will run out of endurance in 5 minutes, 33 seconds, theoretically. I highly doubt you will be fighting that long, except when soloing a pylon or AV. Besides, Dark Consumption more than makes up for that.
After looking at your build, I noticed your toggles lack endurance reduction and your defense isn't soft capped across the board. Phalanx Fighting should not be slotted with defense. A Kismet or LOTG goes best in it.
If you need to look at other builds, I posted the one I am currently using. It doesn't have purples, but it can be easily upgraded for them. Just do a search for my posts in this forum. I posted it in another DM/SD thread.
So I'm trying to make a DM/Shield build that can run the MG -> Smite -> SL -> Smite chain with endurance efficiency, and I decided to take my first stab at the calculations necessary for it. Here are the numbers I've come up with:
Endurance cost of the attack chain: 3.25 end/sec
Base endurance recovery: 3.82 end/sec (with the approximate +.2 end/sec from the PS proc included)
Toggles/AD end use: .94 end/sec (assuming I hit AD every time it's up)
When I calculate my net endurance recovery, I end up with -.3 end/sec. If this is the case, I come to you for help in finding some extra endurance for my build. I'd like to keep melee defense at the soft-cap with ranged defense at 40% (or close to it). I refuse to slot the Glad Armor unique, that's just a wee bit too pricey for my tastes.
Here's the build I'm working with for the calculations. If any of you math gurus wouldn't mind taking a minute or two to check my math and possibly give me a hand with the build, it would be greatly appreciated!
