New tank looking for some tips to be a better tank!!

[Grux]

Protip:

Flash will be your #1 snap aggro, especially when dealing with more than 2 mobs.

Before level 40, you will only have access to Sword Oath. Make sure it's on full time as it increases your damage done (thus directly increases your aggro generated on mobs).
At level 40 and above, you will have access to Shield Oath. Use that from now on when tanking.

Your most used combo will be:
Fast Blade (low aggro) > Savage Blade (medium aggro) > Rage of Halone (stronk aggro).

Advanced protip:
Spamming flash may be the obvious solution of getting aggro - and it is what most tanks are going to recommend.
This is true. It also depends on several factors:
1) are the mobs grouped together for your Flash?
2) are your DPSes going ham immediately without mustard before you wait for the mobs to be grouped together?
3) are you speed running or grouping up more mobs?

You can choose to spread the combo on different mobs.
Remember what I said about your combo?
Fast Blade aka FB (low aggro) > Savage Blade aka SB (medium aggro) > Rage of Halone aka RoH (stronk aggro).

Scenario 1: Mob A and B.
Here is how you spread combo (simplified)
FB on Mob A. SB on Mob B. RoH on Mob A.
The result will be, mob A will receive the low and stronk aggro - Mob A is also generally the primary Mob your DPSes will go ham on. It's no problem as you already have RoH on Mob A, it's pretty difficult for DPS to peel them off you. What about Mob B? As your DPSes will be targeting Mob A, there will be little aggro placed on Mob B - and you already have the SB placed (medium aggro). So both Mob A and B will stick to you.
And then, you can switch them around, FB on Mob B, SB on Mob A, RoH on Mob B.
What the above means is that you've successfully done full combo on both Mob A and B in 2 rotations.
This is generally better than doing full combo on Mob A then full combo on Mob B, because by the time you have full combo on Mob A, Mob B is already targeting your healer. Also some DPS target different mobs.

Use your OGCD abilities like Spirits Within everytime it is up. More damage = more emnity.

Advanced protip #2
In the event you're speed running, or gathering up more mobs before your party clears them, it is advisable to alternate Shield Lob on mobs.
Run > Shield Lob on A > Run > Shield Lob on B > Run Shield Lob on C > Wait > Circle of Scorn > Flash > Flash > Flash > Pop CD > Pop Soda.

In the event you're speed running across packs of mobs.
Run > Flash > Flash > Run > Flash > Run Flash etc


TLDR:
Shield Lob > Flash > Flash > Flash > FB on A, SB on B, RoH on A/C/D etc.
FoF often. Spirits Within often. Pop CDs often.

You can and should use Spirits Within; however, do your best to think consciously about doing each time. Don't assimilate it into your autopilot. If you reflexively use it every time it's up, you will reflexively get the party hit by silenceable attacks later when it matters, and the piddly bit of enmity you managed to eke out won't mean a thing when the party's dead or paralyzed.

since shield swipe is only limited by the GCD, other than if the cast is really short and you happen to activate the GCD right as the cast starts, what's wrong with using SW on cd and using SS to interrupt?

Only downside of this is that there seem to be frustratingly few instances where Spirits Within's silence ability actually matters. In most of the content, at least in my experience and testing, it's far more useful as a DPS boost than an interrupt. I'd love it if it worked better that way, but it seems to have the same problem as Tempered Will, wherein the developers ignored its unique 1s silence effect in coding the majority of abilities in endgame.
