+1 relic weakest upgrade for tanks?

[RhazeCain]

Recently my FC had to use an alt tank (PLD side of WAR main) for coil 1-4. That meant plain relic where normally we're accustomed to +1. It was a noticeable difference. DPS occasionally were threat capped, and you don't want that. Still won though.

As WAR myself there are times when you REALLY want every scrap of agro. Adds spawning mid-fight is biggest example (turn4, Cad split in turn1, Garuda clones). Also, if your DPS is REALLY good they can get threat capped/take agro on just single boss (ex: top shelf BLM going full burn with Foe Requiem). Pretty unusual for that to happen, but it's possible.

Exactly. Even running AK without being really on your game it is very hard to hold aggro against 2 geared out and +1 weapon dps that know their rotations.
