Have there ever been winged warrior in previous edition of the list? If yes, why have they been discarded? Were they to powerful?
Yes, they've made appearances from time to time, and yes, they're too powerful. They make for *very* fast infantry swarms that can race around the battlefield, completely swamping the enemy.
And, while it might be realistic, it's no fun to play against, so they've been removed.
They may make another appearance in a future Tyranid variant list, but they won't be likely to appear in the "core" Tyranid list.
