Something interesting this pack does is give you as pre-built mob farm (or more specifically, all of the contents in a barrel and a schematicannon with which to build it) to start with - it has two levers, one that turns on/off the lights and one that opens up the slot to kill mobs manually (there is no automatic kill system).
I find it not too bad - the mob spawn rate is ok (there's only 5 blocks of this version's equivalent of cursed earth below these vector plates) and it took zero effort to make.
I'm going to need to use it as my first source of source - the vitalic sourcelink is the only source generator I have access to, and I need to progress through ars to continue.
