Yes, of course :D. Mate, think about it, you have a vulkan shotgun on a BS11+3 platform that moves 10 inches per order and can drop smoke on 19. If you're playing in a tightly packed table or your opponent has no MSV2, they can run amok along a flank and totally wreck shit. Ren'ehk has killed TAGs doing this more than once. Sure, they do deploy line defense just fine, but that's for turn 1. Turn 2 and 3 they will be up at their throats.
I mentioned in the Alien Names thread that I named all my MAF models (they're also characters in one of my stories.). Ren'ehk is my oznat. She is awesome. I'm getting my anathematic painted now, after it's done I'll get some games in with Vanilla combined again and see if it makes for a good Rambo too.
