My problem with Illic is for a "stealthy" character the model is massive. In the pic with him and the other rangers he towers over the other models while perched on his stone and the gun sticks way out. It may be just the paint job but if he had a couple more spikes he would look more like a Dark Eldar than craftworlder (yes I know he is an "outcast"). If he's expensive points-wise or has lackluster rules I'll pass.
The real mystery for me is the Wave Serpent. If they don't give it assault rules then all these improved aspects and CC option wraithguard units will have to footslog it across the table which in the current shooting meta is not a realistic expectation even with the new move-shoot-run ability (and I'm assuming Fleet).
I seriously doubt that they will make the Falcon a DT as that would be broken and you would never see another wave serpent again...MSU falcomechdar would be everywhere.
Those people with the WD batrep have anything to say about what the Wave Serpent did in the game?
