Yeah, totally agree with Elta and da Man above. EoK tanking was where I found myself obsessing about AC, AC, and where can I get more AC...
I tried to take my SK from Darkened Sea (wearing TDS T2 armor) straight to Lcea and do EoK T1 named. I got wrecked. Even bad trash pulls would spike him down. I had to backtrack and buy the SK some Broken Mirror AC gear from the vendors. As da Man noted, some of the TBM jewelry can be aug'd in such a way that is is insanely high AC, even better than EoK drops for AC alone.
I'd suggest you just grind your SK to 106 in easier content and buy a Conflagrant set including augs. I was PL'n another tank later and did this, it made EoK T1 pretty easy.

Are you still using roughly this
100 SK ini you posted?
I had to up my KA defensive disc use + lifetap heals when I moved to EoK too. My TDS SK ini was very simple, for early EoK I was using everything I had almost on cooldown.
I used Vizat's Carapace on 3+ trash pulls since I has a nice duration and fast cooldown. Doomscale Mantle was my default Named tanking disc, once the minute wore off I'd pop Vizat's Carapace or Unholy Guardian. Reaver's Bargain is nice too, but I'd use it manually since I wanted to always follow it with Tought Leech when my endurance ran out. You could maybe do that via condition now.
