After playing Nid's through the Long-Fang-Spam Era (tm) I'm excited to actually be able to use my tyranid warrior models again.

Anything that wasn't Eternal Warrior (ie, T6 stuff MC bugs) weren't getting instantly killed by anything other than force weapons anyways. For most people, it's business as usually - except you might see stuff like...I dunno...raveners or skrikes. heck, ripper swarms might make a come-back. It gives Nids options. which I don't think is bad at all.
