Noob 1500 point list

[nuckifyabuck]

First off, just want to say hello to everyone. Figured I would start playing (got a few of my buddies here in Afghanistan that are all starting to play as well) and have a good idea on how I want to play Tyranids. I've always thought of tyranids as a pure swarming army and decided to go with that approach. Here is the list I want to run, 1500 points. Was going to see what kind of tweaks I could do to it.

1490/1500

This is my first army list so I know there are probably tons of things I can do to make this list better. My whole philosophy is tons and tons of fast troops, using gargoyles as distraction, and then overwhelming with the Horms and Terms. Anyways, thanks for the help and criticism ahead of time.

I think you could do with some more anti-tank. Right now all you have is the Tyrant and Tervigon in close combat, and buffed gaunts can take out AV10. Your list is going to murder infantry-heavy lists, but tanks are going to make things very hard for you, and you have no way of dealing with flyers.

I hate to repeat the boring mantra of: Hive Guard, Hive Guard, but sadly they're really something we need to provide ranged anti-vehicle punch. It's a sign of poor codex design that we need them, but hey, it's a poorly designed codex and we have to live with it.

Zoanthropes could also do the job, and would provide your swarm with more synapse. The downside is their slightly shorter range and less resistance to small arms fire. Oh, and Hive Guard don't need to see whereas Zoanthropes do.
