ESOHead has done some work to patch up their database. They still have a nightblade skill in the Assault line of the Alliance war (previously it was wrong the other way around).

Imperial - Races - Esohead - Elder Scrolls Online Database
Here's the full skill map with a simpler interface (which lends to fewer mistakes):

ESOHead will clearly be better once they figure out their database glitch.
It shouldn't be anything extreme, at least. I recall reading about some of FoH's raids in PoP. Didn't one run something like 12 hours, with everybody hitting the same buttons over and over? Yeah, that doesn't need to happen. A good 30 minute battle against one of the hardest nasties out there for legendary loot and bragging rights wouldn't be too horrible though -- especially if it keeps people on their toes throughout. There's a big difference between cast -> sneak -> jump -> block -> cast -> block -> etc for 30 minutes with six full groups and something like taunt -> taunt -> taunt -> taunt -> ... for 12 hours. Long battles should only be included if they're fun enough to seem short.
