It could also help for him to be Combat with Reinforced Leather to further reduce damage after Feint. Even Improved Recuperate wouldn't be useless here as that grants -6% damage taken for the duration.
The most important thing to note is how Feint works with the client and server. At some point, I think around 3.1, Feint became very weird about its usage. If you were rapidly going in and out of melee range of the target and trying to use Feint you could end up seeing the GCD going from supposedly using it, but nothing actually happened. There's no real explanation for this. As far as I can tell this only happens when trying to use it at the same time as going out of melee range by about 1-2 yards. Of course this can easily happen when the Rogue is trying to stay in melee with Morchok while he's being moved over to the crystal soakers.
As for Stomp doing double damage to the person closest to the tank, it appears to be intended. In 4.3.2, they're changing the Dungeon Journal entry (and hopefully the tooltip) to say just that. It seems that the Dungeon Journal is plagued with many errors like this. My best guess is that the errors are from early alpha development designs that they changed over the course of the PTR, and they forgot to update the Journal. For example, it says Deathwing's Elementium Bolt hits for 390,000 Fire decreased by how far away you are, and then hits again for the same amount every 5 seconds. I'm sure most here know instead what happens is it ticks for about 18K every second.
