It's been a LONG time since I last put up a post so I thought I would share my thoughts on my Tyranids that I have been trying. My lists have been made using units which at least at MAWS don't get used and as far as I know have been shunned in most gaming circles.
Firstly lets look at my favourite unloved Tyranid, the T-fex. This beast costs 250pts basic which is a hefty lump of points, but for that you get 6 T6 wounds with a 2+ save, plus a Strength 6 Ap4 flamer which can fire 20" (12" plus the 8" flamer) plus two other weapons (cluster spines and a thorax swarm) it can also fire all three weapons because it is so awesome. It can take some upgrades but the only worthwhile one is regen costing 30pts. The fleshborer hive just isn't worth the 10 points it costs.
Next I tried out the Harpy, I'm still unsure on this guy as he didn't really stand out, but he took out 2 war walkers and blatted a squad of guardians. But he is only T5 with 4 wounds and a 4+ save, which means Heavy Bolters will shred him if he is left in the open. He has some good abilities like his Screech which halves the enemy's initiative the turn he charges and he can drop spore mines (but only once). Having twin-linked Stranglethorn cannons is a bonus and it isn't worth upgrading to venom cannons. I would leave the regen at home even though it's only 15pts. As a distractive unit or a support for a Trygon, or the Parasite it is a decent buy at 160pts.
The last unit I tried which I personally thought was a bargin buy was two Venomthropes. I have heard alot of negativity about these guys but I loved them and will include them in every list I use from now on. Giving my big monsters a 5+ save makesa huge difference, It saved a tervigon from being blasted apart in turn one from a full Eldar shooting round and kept various others alive for a few turns. This frustrated my opponent greatly and took great delight in blowing them apart with missile launchers, I did however forget about various rules that these guys have, like when an enemy assaults a unit within their spore cloud range they have to take a dangerous terrain test!!! At 55pts I think these guys are a bargain and will definatly help keep Tervigons alive and spawning. Just remember they are not like most Nid units they are purely support and will do well being kept behind the Tervigons they are protecting.
Well they are the three units that rarely get used or considered at MAWS but I think we will be seeing more Venomthropes around.
Feel free to leave your thoughts on these three and if you like, dislike or would consider using them.
