Servents of Grenth wastes split

I'm brand new to underworld runs so I thought that I would try out a few heroway builds with my brother to get a feel for it before I tried any SC's.

We ran 2 RoJ/Prot, 2 Icy Veins healers, unsteady ground ele and a tease channeler and were just c-spacing through everything. I ran a standard imbagon and he ran a standard pve dagger spam with flashing blades and "SY!"

I was curious about the quest in the title, what is a good split? Since you don't know precisely what skills I used maybe just some general advice on this quest?

Many thanks!
Apologies if this should be placed elsewhere, it seemed appropriate here

For a balanced team with decent killing power, no split. Have 7 people camp the spawn area and fan out well enough to grab all the aggro. One guy gets the quest and runs over to join.

Of course, if you lack killing power, you'll be hopelessly overwhelmed.

Plan B is a 4-4 split.
