So, this is what I've done:
Dark elf dragon night.
Head: pelinals/ heavy/ infused/ prismatic / outlaw motif.
Chest: Trainee/ heavy/ reinforced/ prismatic/ red guard motif.
Legs: pelinals/ heavy/ reinforced/ prismatic/ mercenary motif
Waist: trainee/ light/ training / prismatic/ redgaurd motif
Hands: pelinals/ heavy/ divines/ prismatic redgaurd motif
Feet: pelinals/ heavy/ divines/ prismatic
Neck: trainee/ arcane/ wep dmg
Rings: trainee/ robust/ healthy/ wep dmg
Sword: endurance/defending/ dmg enchant/ covenant style
shield: endurance/ reinforced/ prismatic/ covenant style
Inferno staff: willpower/ precise/ flame enchant/ covenant style
Gives the DK 35k health, and 26k mag & stam, when on sword and sheild bar.

This "build" is nothing new I know, but I really enjoyed playing it. Ive been trying to make a perfectly balanced build since game launch, and I'm sure this is the best I'll ever get in ESO. This buil is the only reason I'm still playing ESO, I got bored with fotm,meta, and slowly being forced into the holy trinity a long time ago. I desperately wanted this build to be viable in endgame content so I did the only thing I could think of to make it happen. I made four of them. Hybrids by themselves in this game suck, but a gruop of 4 can be good right? Maybe?I convinced three buddy's, a sorc, a Templar, and a nightblade, to put this suit on promising that it would be fun. They were in the same spot as me, bored and about done with ESO.

The sorc was the first to try it ( not easy to convince long time meta players to try something this ridiculous, but I know weebles, send him a suit of armor in the mail and he'll put it on lol). Me and the sorc did some testing, dungeoning, the usual... saw some potential in this. Next one to get the suit was my longtime healer. Didn't work out, can't take the healer out of that guy anymore, so we had to take him out of his comfort zone. He begrudgingly agreed to level up a nightblade. ( this build will not make you a heavy armor healer, he ran out of magic a lot). So I convinced a friend who had quit playing the game a year ago to log back on with his Templar. He was always a tank anyway, not much of an adjustment for him.
Basically my dk runs the fire staff, sorc runs the lightning, nightblade runs the ice, and Templar runs the resto. Sword and sheild on the other bar. Finally got to play as a full group for the first time about two weeks ago, and I must say the results were better than I'd hoped for. I would go into detail about skills and rotations, but this post is getting long enough and I haven't even made my point yet.
It took us lot to get to this point, resources, grinding for gear( I had to get all the trainee pieces myself, part of the deal. Lol). We're not at full power as a group yet, but the excitement is back. Something new, different, and challenging to keep this group playing together. The sorc still insists he will never play his glass cannon build again, so he must be enjoying it. We all had dreams of going head to head with Vdsa once we got all the tweaking done... and then we read the pts patch notes.
I will wait until the patch goes live before to see how bad the heavy armor and trainee nerf hits my little hybrid group, though I can't say the same for the others. I don't understand the nerfs.. trainee not being used as intended? Using trainee in this build has taught everyone in the group a lesson in sustain an class abilities. No proc sets to count on for heals/damage. Cauterize is actually crazy helpful in this group, didn't think there was ever a use for that skill till now. That just one example. "It's called trainee for a reason". Well I'm training an entire group of hybrids with it right now. Lol. If it's OP I don't see it, a pure min/max build is definitely stronger than this. If it was only intended for newbies, then don't let us have cp160 versions of it.
I fear the soon to be nerfs will inevitably force us back into the meta, fotm, Holy trinity, whatever.... and I will lose my group to another game. It was fun while it lasted I guess, we took those hybrids through some crazy stuff. Hell of a ride
