Based on this Article over on Best Overall: http://bestoverall.blogspot.com/2011/03/tyranids-sinsynns-riposte-reposted.html#idc-container
This got me thinking (oh noes!). I've actually in the last 2 tournaments knocked out Mech IG twice, Mech BA's once, SW's once, DE once, and Necrons (which don't count). Not perfectly optimized (though some were close) but a none to shabby record against the "dominant" 40k codexes. I say that because these games and my playing of most of the above codexes has led me to the thoughts that'll make up this series.
First off in regards to the article above I've come to the conclusion that for me the point investment in Tyrano's isn't worth it. Let me explain why though. It's not the actual points they cost. It's the fact that they actually make target priority easier for my opponent and the core to any successful Nid strategy is to truly make target priority a no-win for your opponent.
My heavy supports revolve around Dual Dev Fexes and Trygons. My lists are constantly evolving but the core elements remain the same lately:
Prime w/Dual Boneswords and Toxin Sacs
3x2 Hive Guard
2xTervigons w/Catalyst, Toxin Sacs, Adrenal Glands
Carnifex w/Dual Devourers
This is the core of almost any army I am building. Now I've been building toward an 1,850 force that works well due to Adepticon but a lot of the ideas I've got running around will work fine with a little supplementing at 2k. Back to the above though. It provides your solid core for your force. You have 3 can-opener units, 1 moderate can-opener which is a nasty exposed unit shooter and doubles as a darn fine CC unit. And you've got your scoring core. It totals 1080.
That total leaves you with plenty of space to tweak to your specific style. It allows you to add your chosen disruption element, your preferred hammer unit, and your personal style of speed. These three things are essential to making a Nid army that works. But these need to be done while also creating a target priority nightmare. It's a very tricky and thin line.
So from here where do we go? I'll cover more in Part-2
