Ah, welcome to the bad habit of using the nastiest thing you can get your hands on as OPFOR. Cascor, Yolu, Kor-Lyan, Hyach, all suggested on the boards (I get my D's and E's mixed up sometimes, but I have the numbers), I had a go at them- and tested them to destruction with my usual Jashakar-Omelos-Targrath combo. If anything survived to the fourth round, that's how I knew it was so bent as to be wildly unusable.
How we got on to the subject I don't know, but- RN capital ship losses in WW2;
one battlecruiser to heavy ship gunfire (Hood), one battlecruiser, one battleship to aerial torpedo attack (Repulse, Prince of Wales), two battleships to submarine torpedo (Royal Oak, Barham);
one carrier to capital ship fire (Glorious), two carriers to aerial bombing (Ark Royal, Hermes), two carriers to submarine torpedoes (Eagle, Courageous); ship to ship gun duels were the exception, it's not really a model ACtA ought to be taking much from.
Operationally speaking the tourney Avioki actually makes more sense, when you think about what it's for. I throw the fluff away and look at the numbers, and imagine they were meant to be there. The standard Avioki is actually very hard to kill. No interceptors; proprietary tech of one Brakiri corporation rather than another, maybe, but they're unnecessary if you expect to be hit by heavy beam weapons. It's a rhinoceros rather than a tiger, though; it's slow loading, non- penetrating beam is not going to land very hard on anything. Avoid being killed, yes, but it's not very good at killing.
The tourney version, with extra range and AP on the main and no flank weapons, is much more obviously built for a specific role as a spearhead unit, intended to give them a measure of equality against major powers' heavy warships. It can't manage that and protect it's own flanks and rear as well, so it needs an escort group.
