awww show me on the doll where the flyrant touched you.
edit: I actually agree with tyson, although not exactly how he phrased it. I think it's dumb to not have 30k in 40k events. But is it okay to have 40k in a 30k event? part of me thinks "Sure, why not!" because it would hypocritical otherwise. The other part of me thinks 40k stuff is actually better and would ruin the 30k vibe*. For the first one - I'd play it conservative and just run 30k only. No Xenos (even though Chris' list of xenos is actually pretty legit). Later on - play it by ear.
*30k can't ruin the 40k vibe. Playing 30k is just handicapping yourself vs 40k armies. But some players like the challenge and want to play with their toys.
