hmm bit of a shock to me: it seems like it lacks melee (other than the WK).. a shooty Tyranid list is bizarrely poor in
cc and this is too (ie. if/when people figure out they can melee you, you're doomed

) .. there are also no hive crones.. and no tyrant bodyguards, and they are (I think) pretty good.. also you have 2 fliers who can pack the dakka, so why not just have one on the ground and get bodyguards, don't get me wrong Flyrants are the best unit Tyranids have, but for me at least one needs to be a close combat nuke bomb.. also think about zoanthrops they help ur shooty hive tyrant stay alive. 9 dire avengers.. hmmm I would get 5 fire dragons.. more punch and you have termaganuts for the other good stuff.. the jet bikes will struggle with 10 odels physically not being out in the open all the time (it's a model size thing) the best thing is either think about shining spears (they get 2+ jink and can hit and run melee after so do not need conceal) and if you can get fortune from the jetseer all the better!
IC him into the squad and use them for wounds - if you don't do that get mantle for the jetseer
*phew*
