Actually, if you run a 200 point build with Nom and UH Lobot, then you just bring in the MTB and 3 Grans with Lobot (hopefully you have some other fodder in your squad as well), then set up such that you can blow one Gran and trigger Scarification on multiple pieces right off the bat. Again, I don't particularly like the idea of intentionally hurting my own pieces, but if it's only 10 damage, might be worth trying it.
Probably depends on what your opponent is running too though. If they have high-powered Accurate shooters, might not make much difference, as you really won't be able to expose the Priest much anyways, because they'll just shoot it. A lot of it comes down to match-ups. Luckily, Accurate isn't as common anymore, and most pieces with Accurate can't do more than 40-60 damage per round, so usually, can keep the Priest alive with a Bodyguard pretty easily for at least one round. Plus, that shooter then has to waste 1 to 2 rounds trying to kill your tech, rather than dealing with the main Vong pieces themselves, so that can be like shooting yourself in the foot as well.
Honestly, for me, that's one of the biggest issues I have with the Vong still. In order to use the Priest or the Shaper, you're forced to run a bodyguard as well, otherwise, they'll never survive long enough to be useful. I like the fact that they are SAs, so they aren't stopped by Disruptive, but it also hinders their usefulness, especially if you're already running Mouse Droids to help with Yomin's CE. It's sort of a toss up I guess. Can't have the best of both worlds.
Hmmm....what about this for 200 points then:
