So nids in the new edition get no allies. Seems like a real downer considering everyone else gets them...that and nids being the weakest army.
I started playing nids back in 2nd ed and their codex from back then to me is a real inspiration of what they could be like when they get a new book (which prolly won't be for a long time).
See tyranids are just different than every other army in 40k. They're the only army that is not a military, has zero culture, no intelligence, and no home. Other armies may fight over a bridge to maintain supply lines, tyranids don't. They just eat the planet, reproduce, and move on. All the things armies are getting access to in the new edition like allies, terrain, psychic powers, secondary objectives all don't really fit nids.
Back in 2nd edition this was still true and back then there were universal wargear cards, universal powers, stratagem cards, and objective cards. But none of them applied to nids, so nids got replacements for all that stuff in their codex.
It would be cool if GW did the same for nids in 6th ed. Imagine if nids couldn't get the fortifications that everyone else gets, but instead got nid terrain from the nid codex (like maybe a chimney that spouts miasma, or a synapse beacon). Imagine if nids got their own special FoC since they can't take allies. Imagine if nids got triple points from completing secondary objectives, but no points from the main objective (forcing players to kill as fast as possible, kill the enemy commander, and get into the enemy lines as fast as possible...ya know, like nids should).
