Hello there, here you are my current tanking build for a Jedi Guardian:
Health: 31401 (Buffed by Reusable nano fortitude Stim)
Defense: Chance (21,55)/Rating (1170)
Shield.: Chance (42,33)/ Rating (969)
absorption: Chance (27,82)/Rating (301)
As you can see i'm following the content of this thread http://www.swtor.com/community/showthread.php?t=616779 and, in general, i prioritize mods with high rating lacking endurance (I use veracity variants Implants and earpiece, and i have 2x WH Relic of Imperling serenity). However i've a great problem of squishyness. For example: in TfB SM, the Operator IX dealt to me a damage of 10k with a single laser shot ; in Toborro's Courtyard SM, golden Fury deals to me a damage of 8k with its cleave attack. I'd like to say that in each case i've never been killed but it's very frustrating getting a so high damage in boss encounters. Is there anything wrong in my build? Please gimme a hand-
