Did a search for Nax trash and trash mobs and variations on the same but couldn't find anything relevant so...

Anyone have experience killing the outer ring mobs, the ones inter-connecting the end wing bosses?

Since we are killing faster and faster we are running out of the tier3 set stuff (plate/leather/mail/cloth scraps etc) and was wondering if farming the outer ring would be a good srategy for getting more and the odd chance at zone epix. Mainly am just curious if they are like really hard and not worth it. For example the trash mobs between Maexanna ---> Thaddius.

That's what they are there for....
