SS / LB Farm - The Sulfurous Wastes

I'm currently using this to max out my SS and LB title. I net around 500 SS points and 650 LB points however, this takes me 12 mins and I read everywhere that people manage to do it in 8 mins. Am I doing something wrong?

Take heroes because PUGs are bad, and use the wurm stance a lot. Also, at the shrine for LB points, don't bother killing the enemies next to it as you get 25 later anyway and they waste time. I flag my heroes at the djin whilst I get the shrine, then go over to them.

Ah ok, but what do you mean 'as you get 25 later anyway'? I got 25 margonites, but that included the ones near the LB shrine and it also included the 3 Margonite bosses at the end.

When you pickup the stone thing it spawns extra margonites which you go back and kill making 25 in total, then you kill the bosses (I flag the heros where the extra margonites spawn whilst I pickup the stone).

The tome of knowledge from the Requiem for a brain quest spawns 2 extra groups of Margonites back where Alem spawns, when you pick it up, for a total of 30 without the shrine group.

As for speed tips, 12 minutes isn't bad.
If you're good under pressure, you can free the bosses without killing any of the moniliths, that shaves off a bit of time. :]
