Don't know if I like #2. It's nice, but might be overkill. I can always use a Cloaker Starship.
Mainly it's:
a) a quality of life improvement, not having to do the joint-movement micro or worrying about flicker during wormhole transit (though I think I've cleaned up a lot of that recently), etc
b) an effective speed improvement when "in stealth". Cloaker starships aren't all that slow (iirc) but nothing to transport speed.
Not a fan of #4. I'd prefer to focus on getting them to the target, and not kiting AI ships with the Transports insane speed.
Yea, that's a legitimate concern, but I think just making it a short range weapon would help.
Hahaha, maybe I could make it
melee range, with the cutlass's self-damage rule
Assault
Drop-pod. Ramming Speed!
Though really the main reason I went with the idea of the attack was something that would let you "toggle off" the cloak to get the damage sponge back, which self-hurt melee wouldn't really do.
On the FF-on-death thing that's a pretty optional part of the idea; a per-planet cap of 1 with a 5 second duration would be fine. Or maybe "can only trigger once per 10 seconds per planet" and a lifetime of 5 seconds. Or we can just leave it out; it's just trying to provide some additional support to the troops that just got unceremoniously dumped into combat.
