A warboss is a must for the waaagh benefits.
Same with wierdboyz- their movement abilities are excellent.
Vehicles in general are a toss-up: on one hand, they can give you a big speed advantage, but they'll also tend to break down alot due to the terrain. Be sure to use a reinforced ram. Heheh. I opt against them for more sloggers- 5+ cover saves at all times is sooooo nice.
As mentioned, meganobz excel because they're not penalized in addition to their normal slow movement.
Tankbustas are about like in a normal game...same w/ lootas... though the added cover makes them both more survivable
Again, as mentioned, commandos are good but take up a strategem
Burna boyz RULE
Warbikes may have a tough time getting through terrain, and their 4+ save is less valuable- I'd leave them at home
Deffcoptas could really excel here, though I've not used them
I guess in general I'd recommend loads of boyz
Big shootas will be your friend, as everything you hit w/ rokkits will now get cover bonuses, BS dakka becomes a better option imo
I personally love the demolish building stratagem, and booby traps are fun too. Thats just the Mork in me talking
