I spruced up my tyranid list in anticipation for 5th edition. I decided to go whole hog with outflanking genestealers and trade in the warriors for a couple more lictors. It might be a total flop but I want to play it at least once.
Hive Tyrant - 2 twin-linked devourers, warp field, wings, flesh hooks, toxic miasma, enhanced senses
6 x 8 Genestealers - scuttlers, feeder tendrils
2 x Carnifex - venom cannon, barbed strangler, bonded exoskeleton, enhanced senses, reinforced chitin, extended carapace
Carnifex - 2 twin-linked devourers, bonded exoskeleton, enhanced senses, reinforced chitin, extended carapace
Feeder tendrils are a slam dunk now - 1 point each to reroll to hit? Yes, please. I don't know how well outflanking will work, hopefully the lictors will help to coordinate their attacks. If the hive tyrant gets tired of flying around laying down loads of grubfire, he can join in an assault with either the stealers or the lictors and get preferred enemy, too. I maxed out the MCs to try and keep them hanging around for a while and distract from the stealer assaults. The dakkafex is just a bowling ball, really.
