Hmmm...Wait did I over pull where only there are 4-5 mobs on me at max? Full ilv90 Armor slots plus Dual Hakken, only my accessory slot was for SB, if you are saying that this is inferior, so I suppose the ilv that recommended for the Duns by SE was WAY WAY WAY low... I don't think SE just choose a random number to put up as ILV minimum requirement for the Duns...
@silvach: On paper, yes that sounds about right. However, when apply to a practical run, there are a lot of problems that are presented strictly speaking as Paladin:
1/ The only tool available for Paladin for AOE aggro holding is Flash. And yes, the durations are just like you listed each time you re-apply. However, if you actually did wait for the full duration of Blind to go off before you re-apply, you will have a very hard time to hold aggro against any decent DPS that does AOE dams, let alone BLM. You also risk of losing the aggro to the healer as well in the process. Therefore, to really maintain a strong and firm aggro on a bunch of mobs, Paladin has no choice but to spam flash continuously while either doing the Halone Combo on mobs or the Riot Combo to maintain the MP for more Flash. As a result, 12+6+3 sec for full duration blinding is not applicable.
2/ I normally don't stun the mobs for any AOE pull because it is not effective. First, it really kills your TP if your DPS do a bad job at DPSing, second, you risk of losing aggro on mobs because you could use that 2.5 sec to do Flash or doing the combo. Furthermore, Shield Bash does break your combo as well.
3/Stoneskin is my last resort when it comes to mitigate the damages. I usually go through the list of all my defensive CD before actually stop and casting Stoneskin but normally, I don't have to do that if it is just a Duns run because mobs usually are dead before I run out of all my defensive CD.
That is how I tanked as Paladin.
