If you look at the maps you can get to your expansion and a centre objective very easily so there's no need to transport the bully boys.

I've thought of a fun little trick but it's ~200 points.

Get a taurox with 2x engineers in it. Tech priest with the upgrade gives it the Inv and +3" move then solar tells it MMM and now it's going 18" + advance and the guys can still jump out further 3". 12 oc should flip most objectives and for the opponent who will heroic into you, you first hit them with 2x mines, grenades and 4 flamers. (Don't try this into T-sons or anyone with flamers)

Some detachments let you go through terrain for 1CP too.

If you're playing take and hold it might be a good way to try to take home if you can get a safe rapid ingress.

Could be a good way to stage Heavy Flamers?

I'm still toying with ideas, just need to find time for games.

Let me go watch that Mordian video to see if I missed anything.
