Incoming autistic whining.
I'm hoping for a Tyranid Codex 2.0 eventually. The only way to win with Tyranids as is to plop down 500 Gaunts, squat on objectives, and then let your opponent have fun trying out all his best guns on your shooting gallery while you just wait for your next Psychic Phase so your Zoanthropes might do something. Genestealers are overrated, in my experience, unless you play a very specific and predictable build. They fall like wheat to the humble Slugga, and even volleys of lasgun fire can thin them out dramatically. And then you will probably wind up losing 30 points worth of Genestealers to overwatch on the (failed). There are so many pointless units in the army, from the Haruspex and Tervigon, to iconic stuff like Warriors, Carnifexes and the majestic Lictor. Biovores used to be able to pop off a MW a turn for 35 points a piece, but at 50...well, that's over 12 Termagants for an unreliable MW once per turn.
Basically everything but Gaunts (and maybe Hive Guard, which seem okay until you factor in Instinctive Behavior) is terribly inefficient at what it does. They need to get guys with a genuine attraction to the army, like Andy Chambers had in 2nd Edition, to guide the next Tyranid book.
