I have only a few tyranids (A flyrant, carnifex, zoanthrope and like 20 or so gaunts, and the codex). I'm thinking of expanding my nids by building up a skyblight / skytyrant list with like 7 FMC or something absurd like that. My question is - should I even bother with this? Are tyranids really worth the money or the time? I've heard so many awful things about them online, and I'm not sure if this would be a waste of money. It just seems like they don't have answers to so many things like high AV values. So, tyranid players - what makes your bugs successful? And what makes you keep playing them?
