Flash

[Skull_Angel]

ive started using this rule on flash.
if its an AOE heavy party i do the following:
(Flash x Number of Mobs) +1. So if there are 3 mobs, i Flash 4 times. this seems to hold adequate threat during the initial AOE-fest. then i start working on my rotations, throwing in a flash every rotation or so to keep threat on additional mobs.

I've used this rule for helping people learning to tank since somewhere around 1.23 and it's great advice for people just starting out in most instances. Once you have a good feel for AoE threat generation, you can expand upon it with rotating different abilities after the initial AoE threat snap [situational].

Flash also blinds the targets, its pretty useful when dealing with lots of mobs. If the target is blind for a time, it will make it so you take less damage. That also makes it easier for the healers to keep up with lots of monsters going after you. If your starting to get owned, and/or healer is struggling to keep up. A flash can be pretty useful, if all your other buffs are down. Its useful even if they are up.

Note: It only blinds if you're a PLD. WAR don't get the trait to blind with flash.

Flash is an essential tool for PLD in speedruns / long/ large pulls.

Bray HM for example. Run through and flash / body pull everything. Once gathered, flash+RoH+flash. Riot blade combo > flash many times using CoS when up. Oh and definitely use Fight or Flight with CoS....get moar hates!!!
