Deamon bloodletters or tyranid genestealers for a base, probably behemoth to keep the red tide team going? Was thinking something melee heavy as opposed to my shooty marine and tau armys to do something different. Right now my game group if fairly marine have so thats what i will probably be playing against the most. Pros and cons of one over the other? Leaning towards nids for psykers.
Pure Daemons are a difficult army to make work. You have very little shooting, and with Khorne you're giving up the Psychic phase too. They have some good units, but are better in support of other Chaos.
Tyranids on the other hand are a diverse and interesting faction. Depending what your bring, they can do well in any phase. They're a bit of a jack of all trades, master of none. But they are always fun. Power wise they are in that sweet spot of good enough to hold their own but not too good that that they get hated on.
One more reason to take nids then. If i go for the nids army what more then genestealers should i get, other then HQs
, to keep it meele heavy?
Key Tyranid units (imo
Hive Tyrant - it's basically a Daemon Prince. It doesn't have Character Protection, but it's still ace. A tough beatstick with psychic powers.
Neurothrope - the cheap option, they are strong psykers you can hide behind your hordes.
Old One Eye - brings the hurt, and does have Character protection.
Swarmlord - Hive Commander is amazing. Use it on Old One Eye or a big mob of Genestealers
Genestealers - extremely scary melee fighters. The only issue is getting them there unscathed, as they are a little squishy. T4 and an invuln, so could be worse! Make them Kraken to speed them across the battlefield.
Rippers - cheap, relatively durable, free Deepstrike. These things are great for filling up detachments and for tarpitting.
Gaunts (both kinds) - cheap horde, they have their uses for screening and objectives.
(You'll note that's 4 separate Troop choices I've listed as good. Tyranid Warriors can be decent too actually. What other codex has 5 usable units in the Troop slot!?)
Venomthropes - I love these guys. They are vital to keeping your army going in my opinion, with their -1 to hit aura.
Hive Guard - our best shooty unit. Impaler Cannons are generally considered best - essentially a double Krak missile that can shoot through walls! Keep these close to your Venomthropes, and use the Strat on them to shoot twice.
To be honest, not much to shout about here. The whole army is fairly fast already though!
Tyrannofex - good shooty monster, take acid or rupture cannon. Both solid.
Exocrine - another good shooty monster!
Carnifex - quad Devourers are pretty damn good. Melee ones less so, but fun. I magnetised mine anyway, so can have any of the huge number of possible loadouts!
