Well, I just finished the test, and let me say, the results are very encouraging.
Advent:
Halcyon: level 3, 2 ADA, 1 TP, all fighters
Upon Leveling: Second level of TP
Radiance: level 1, 1 Det Am, all fighters
Upon Leveling: EAA, Second Level of Det AM, Second Level of EAA
Repair Platform: 4 uses on Radiance, 0 uses on Halcyon (manual use when the Radiance went below 200 hull)
Vasari:
Skirantra: level 3, 2 SB, 1 RC, all bombers
Upon Leveling: Did not level
Skirantra: level 1, 1 SB, all bombers
Upon Leveling: Did not level
Result: Both Advent ships survive. Radiance at 230 hull. Halcyon at full health.
Description: When I began the test, I discovered that if I set bombers to hold position, they would not reengage after their death. For that reason, I switched them to traditional attack styles. Also, the bombers would target the Radiance by default, though had they attacked the Halcyon, the result would have been the same. The interesting part here was that it was incredibly easy to stop the bomber spam. 7 squads of fighters was able to pick off bomber squads very effectively, thus leveling the playing field drastically. Of course, they were helped by a level of TP, but the point remains. They worked, and very well at that. The Halcyon did one thing only, defend the Radiance.
It should also be noted that the AM on the Skirantras dropped incredibly quickly (and during this time, the Radiance leveled up the first time). While there was quite a few issues at the start, once AM was depleted (which happened within about a minute), bombers were no longer as much of an issue. The Radiance was however getting weak at this point. In fact, the very moment the level 3 skirantra dropped to zero AM, I got a warning saying that the Radiance's shields were down.
After this, the health of the Radiance continued falling as did the hull of the level 1 Skirantra. Somewhere within this time, it leveled up due to the exp generated by dying SC. The second level of Det AM was a huge buff to attacking the Skirantras. Doing so more than doubled the damage dealt by the ability, causing health on the first Skirantra to plummet. Bombers were still taking their toll on it though, and during this time, I had to use the Repair Platform three times to keep up with incoming damage.
Then the thing I had been waiting for: BOOM! The level 1 Skirantra was dead. With only half the bombers to kill, the 7 fighter squads quickly overpowered them and gained air superiority, though I was forced to use a repair platform once more. Eventually, this led to all bomber squads dying and respawning one at a time. Due to this, I sent all my fighters in range of his Skirantra to deal some damage between bomber spawns. Also, the second level of Detonate AM yielded a dramatic drop in his hull. The end result was a victory for the Advent.
Analysis: While I was forced to use four uses of a Repair Platform, that is not out of the question for an actual battle. Doing so would not be hard to come by at all. A single use regenerates 300 hull over 10 seconds, which means that the Radiance needed an additional 1200 hull to survive the onslaught of bombers. Once again however, I would like to point out that any person who has scouted ought to know that his enemy is coming with dual Skirantras and as such would of course put up defenses such as RP's anyways. What I did was nothing out of the ordinary, but instead showed what would happen in a real battle. Skirantras die. Its simple enough. Advent won, Vasari lost.
I may do other tests later such as a Sova/Dunov combo, but not right now... I'm not good at TEC due to the fact that I never play as them so I would not know which abilities to go with...
Further Analysis/EDIT: I meant to post this earlier, but it should be mentioned that the goal of this experiment was to see what it would take to keep both capitals alive while destroying both enemy capitals. If I would have not used any repairs, the battle would be expected to have been a tie as while one race would have died first, the other would have been killed off by the SC of the first before the automatic death of SC. If one chose to use any number of repairs, the Advent would have certainly won.
