Ah, so then in order for the broken Terminators to embark the THawk would have had to have been landed and the Terminators would need to have used their withdraw moves to embark. Right?
No problem on the playtests, thank Matt though as he's not a fan of planetfalling armies

.
I'd like to go best out of 5 with this list and then run a best out of 5 playtest with another list using scouts with Sniper, Land Speeder Storms, RG Assault and Storm Eagles.
Re: the stuff we've already tested
From our after game discussions I'd say the Planetfalling Speeders are neat but no great boon. It's guesswork as always as they can touch down where they can do a lot of hurt or where they're sitting ducks. I definitely don't think it's overpowerful that they're planetfalling scouts, they can stretch out their landing area quite a bit but the scatter helps alleviate perfect positioning (even with a re-roll it's hard). Plus, if they're really stretched out a clipping assault will work them over.
The free Land Speeder Tornadoes feel right so far. I know Hena just bumped these down on the main list, I don't think they'll be a problem.
I've used the scatter re-roll once or twice a game on the Tacticals and Terminators. It's useful but there have been times when it did nothing for me. Haven't had a re-roll that's come up worse than the first one though.
On the Terminators, they're definitely more flexible when they teleport but the drop is a nice option. At some point I'd like to test a list with 5 formations of them dropping. I'm sure Matt is sighing as I type.
