7.8 Concentration / Fury SWTOR Guide

Step 1: Build 30 stacks of Centering.  Activate your out of combat health regen and build 30 stacks of centering.

Once your target hits sub 30% HP, start substituting in Dispatch in place of the "slashes" for more damage.

So, after parsing a great deal with concentration, I have found what I believe to be a comfortable way to insert inspiration into my sequences.  When Valorous call comes off cool down, here's what I do.  I save it and wait until I get back to the "Zen" Block.  I hit Inspiration Before I hit the Focus Burst in that block.  I then immediately hit Valorous Call + Zen, and then continue with Concentrated Slice and the rest of the Zen Block.  Keep in mind that Valorous Call and Zen are off the GCD, so there shouldn't be any delay in your Sequence.

The Sentinel is a bit unique as it has 2 "Raid Buffs"  Inspiration to the left is the traditional raid buff giving 10% damage for 10".  It requires 30 stacks of centering, making it a choice between Zen or Inspiration off the break.

This unique raid buff is on a 30-second cool down and requires selection from the skill tree.  Transcendence gives the raid an 80% speed increase, 10% damage reduction and cleanses movement impairing effects.  I use this on cool down even if I am not moving for most fights.  Save for movement in movement heavy fights.

Last for 12", this ability gives us a 50% chance to dodge Melee/Ranged damage and a 25% Damage reduction to Force/Tech attacks.  It is on a 3-minute cooldown.  It's a strong defensive, but its long cooldown means you will most likely only get to use it once in a fight.  I save it for emergencies, mostly.

This is our self cleanse, threat drop and a 50% DR all wrapped up into one ability.  Note that dealing damage ends the effects of Force Camo Early.

This is a staple of the Sentinel.  Rebuke reduces the damage you take by 20%, so it fits in as a defensive cool down.  However, it also reflects damage back to the attacker.  A common strategy for sentinels is to "stand in stupid" as long as the healers can handle it.  Say we stand in a spit puddle on Writhing Horror, for instance.  Pop rebuke and reflect that damage back to the boss.  As we take damage, we extend the duration of rebuke up to 30".  With our selections from the skill tree, rebuke becomes a very short fused cool down.  Matching its use (assuming we can continuously take a light amount of damage consistently in a fight) with our choice for a permanent 30% AoE DR and the concentration sentinel quickly becomes able to soak an impressive amount of damage while reflecting a notable amount back at the boss.  It's a good practice to get into using rebuke not just on cooldown, but when you know you can take light - moderate amounts of damage without stressing the fight.

A short cool down (35") defensive or movement ability.  Blade Blitz can take some practice to know where you are going to end up.  You can use this to completely ignore (100% defense chance) high hitting damage types (doom on Dread Guards).  It has a lot of utility once you master it.

This is our other choice (if not taking blade blitz).  A 99% Damage Reduction for 6" has the potential to soak an impressive amount of damage.  Keep in mind that a 99% DR still lets 1% through, so a mechanic like Doom listed above that hits for 136 million damage will kill you through, guarded by the Force.
