I'd spend it on a pair of gorgers, using a little of the extra points you've allowed.
How are gorgers this time around? they are certainly unexpected and thats half the fun, but do they ever do anything usefull?
I love gorgers - when I have "leftover" points, I usually try to squeeze 1 or 2 in. They bring some good things to the table that no other ogre does - namely, ItP (via frenzy) killing blow, ambushers and unbreakable.
Perhaps my gorgers over-perform, but usually they accomplish what I want them to do: and usually that's get rear/flank charges, distract war machines, etc.
People will argue against gorgers because they say that sabertusks (and ironblasters) are better war machine hunters - well, I say if you are using a gorger as a war machine hunter (primarily) then you are using it wrong.
