I want to know why people still think Turn 1 Deep Strike is healthy for this game? It doesn't hinder alpha strike armies (a common complaint) but instead it helps them as they make use of it the most. Getting to dump your army wherever you like turn 1 is not good design, you may as well at that point tell your opponent to not bother with deployment zones and instead alternate placing units anywhere on the board with 9" minimum between any hostile units!
Deep Strike alpha strikes aren't the problem. Alpha strikes in general are.
I've played several games with the beta rules now and I've managed to play around the beta rules and get some massive alpha strikes in regardless using flyers, Blood Angels Scouts, non-DS Jump Pack units and Upon Wings of Fire (Blood Angels stratagem).
In the games I've played I've managed to go first every time (which is skewed, of course). Regardless; not being able to deep strike turn one made no difference, as in those games I demolished huge portions of my opponents' armies before they could react.
Two notable examples for their brutality, using this army:
Captain (JP, Thunder Hammer, Storm Shield)
Librarian (JP, Wings of Sanguinius)
Lieutenant (Veritas Vitae)
2x Stormhawk Interceptors
3x Predators (Predator Autocannon, Heavy Bolters)
3x 5 Scouts
2x 3 Inceptors (1 Bolter, 1 Plasma)
Second game example:
Now, both of those would certainly have been different if my opponents had gone first. My Scouts would almost certainly get obliterated; my Predators would likely get hurt, maybe losing one (Necrons were definitely light on AV fire) and the Guard would've had Scions ready in their second turn.
But the point is that my alpha strikes came with little hindrance due to the beta rules, and those rules actually shut out my Guard opponent's possible comeback by denying him the ability to retaliate.
Something certainly needs tweaking about the game, but it's about alpha strikes in general, not deep striking in general. Maybe they are intertwined, but nerfing deep strike doesn't really curtail alpha strikes, as that's a much larger issue.
