In-character Zelda isnt going to say it, but OOC i think airdropping is a terrible, if not suicidal, idea(which is why Zelda hasnt said a thing)
1) if you airdrop, you are not on the ships, you are not using the power cable, you are running on battery, 3 rounds isnt enough
2) if you fight on top of the turtle, do you bring C equipment and suffer penalties for fighting outside water, or you go without c equipment at the risk(i consider it guaranteed so i'm not sure if -risk- is the appropriate word) of falling into water and..well..sink like a brick , run out of energy and eject?
3) the turtle can simply rotate to toss you into the water, unless you decide to grapple it, which is unlikely to work since it's big and (likely) better at grappling than us
4) neutralize has a 20 dam range, being on top of the turtle doesnt give any advantage as far as i can tell, you can do that from 4 squares away
5) being air dropped into the turtle means triggering the angel fear test mid-air, you risk to land on the turtle and be paralyzed by fear...or run away in fear..or be vulnerable to melee attacks..etc.etc. better to trigger the test while on an allied ship, that way if you get something particularly nasty the ship can move back a bit, to make you less likely to be targeted(while also providing you with energy) while you try to snap out of it
6) you will be in melee with the enemy, i think that trigger the shooting into melee penalty for Zelda and Anya(not 100% sure if it apply in this case, given the enemy size)
In my opinion being linked to a ship is necessary(for energy), the question is if to fight while standing on the ship (using maser) or if fighting submerged(using projectile) i prefer the latter because if you fight on the ship, you must decide if to bring c equipment(and fight at a nasty penalty) or go without, but if the ship sink(even a small blast is enough to hit ship+eva), or if you fall into water, you are not going to get back to the surface and will suffer water penalties(and masers dont work underwater)
while if we fight submerged, it will take a pretty big blast to hit both the evas and the ships and we can use c equipment to move vertically into melee, if we want/need it
