You make it sound so easyApart from a few stupid mistakes, it is always the mines that seem to cause the problem. We have always killed all the adds but the number of adds that spawn the same time as the mines means we just get killed trying to get around the map for the mines or slaughtered while standing on the mines.
Closest I ever got was I was the last alive dismantled the last mine at 25% health and I died trying to get to cover.
I am not fussed about doing it for the triumps emblem but would like to do it before taken king drops and the level cap increases.
Trick that we use is the mines spawn when Skolas gets to 50% & 25% health, so ensure the that the hunter (or dedicated mine runner) in party has just had the poison taken off (before DPS'ing Skolas to trigger the event), that way he can use his super to get the furthest mine and some times the middle one as well, before joining back up to the group. Other two just focus on add clearing.
For small arms Thorn is a left field choice, rather than the normal FB,VoC, while it takes a bit longer to take down Skolas, it rips through the ad's, even the captions stand no chance

When I said 1 hour an 30min I meant the whole thing not just the boss fight
I was going to say it only took us about 20 minutes to get Skolas down
