However, I have now decided to get the publics opinion on this... Does it work?
The whole point here is a Tyrant Deathstar being hit only on 6s to shooting.
The main idea of this is simple. In 5th, units moved at the speed of their slowest model. In 6th, you must retain coherency. So, a Flying Hive Tyrant could join 3 Tyrant Guard, as there are no rules saying he can't. He may move however he wishes, but he must maintain coherency. Now, below are the tools and models I will use to demonstrate. The large base is a flying Hive Tyrant. The Medium bases are Tyrant Guard. This also shows their initial deployment. Consider the White dot on the large base as the Flyrants facing.
Now, declare turn one that the Tyrant is Swooping. He is hit on 6s when shooting. So long as he is the closest model to the firing unit, the WHOLE UNIT is hit on 6s. Now, First turn he MUST move 12" to remain swooping. See below, as to how that would work. Still in coherency, still Swooping. Now, Run the Tyrant Guard straight up, so the Tyrant is still barely ahead, so that you can do the same thing next turn. (If you were to roll 1's several turns in a row for runs, this wont work as it will eventually collapse. Glide for one turn to get in a good position, then keep going.) When moving the Flyrant, he should be at 45 degrees from straight ahead at all times, so that 90 degrees turns can move him consistently.
*NOTE ON THE BELOW: The arrows do NOT show where the model was last turn exactly, just its general motion, as limited by the edge of the picture.*
When in assault range, simply drop down to glide mode and hit things!
Issues with mixed flying units:
I would say that the Tyrant Guard can be assaulted, which would then draw the Flyrant into assault, but that the Flyrant can't be the model assaulted.
Shooting: Templates that hit the Tyrant Guard cause hits, but not the Tyrant.
If the Tyrant falls, the wound from that, RAW, CAN be allocated to a guard.
Added tips: Add a prime for resliency, if the guard die you're stuck walking.
So, any questions or concerns? Of course! But if you see a legal rules issue, and can back it up with cited rules, please say so!
