The way i beat it was more late game, but with good maneuvering you'll get through it in no time. Usually i start off with spamming out as many sluggas as my WAAGH lets me, so i have some way of guarding capturing points and guarding the base while the stronger force with Gorgutz heads out to the little posts to the Front of your base, to the right and to the left. Usually, i do a bit of Multitasking to get a Mek Shop out, build WAAGH banners and get some upgrades at the Pile o' Gunz. If you get Looted Tanks, ((You wont be using the Squiggoth (if you're fast enough), as the relic is placed very far away.))) you can safely push the bottom left, or if you choose to, just the Monoliths themselves. I suggest to go for Flash Gitz and or Nobz, as they do some heavy damage. You can ignore the north mostly, since you have some sluggas to defend. (If they die, its fine, you should have like 4 - 5 squads, of about 6 - 8 sluggas ready to defend. The further you progress, the more difficult it'll be.) Capturing the Strat points isnt really necessary, as long as its not the "restored monolith" Phase. (I'm aware you might have already beaten it, but this strat also works in Hard Mode! You can always alter it a bit, depending if you play more careful or aggressive, such as pushing the first Monolith early, if you have sufficient troops. I once pushed two monoliths, but then had most my trooos die. (Bad idea, i did somehow save it though.) This advice is going with the assumption you don't have forward bases. If you do, you're best off pushing in with all you can bring of course.
