Do we really need a plan? How about a mission statement?

As you've probably guessed from the blog title, this is going to be about Warhammer 40k Tyranids and my continuing efforts to build a better world-devouring swarm. Since the release of our 5th edition codex and the... mixed... reaction to it, I have yet to see anything like conventional wisdom emerge on how to use it. Most of our old builds are gone, and the most we can agree on is that Tervigons and Hive Guard are pretty good. Unfortunately there's a big difference between recognizing "good" units in a codex and building an effective list. Hopefully I'll be doing the latter in the next few posts.
