My main question is about those two capital ships, but I realize that the answer depends somewhat on the other ships one uses. So for context, in Fleet Arena I currently run Home One plus Biggs, Vader's TIE, TIE Fighter, FO TIE Fighter, and Slave One (with Wedge, GS, and Ahsoka as reinforcements; I also have Poe, Resistance X-Wing, and JC that I could potentially use.)
Anyway, I've been having some doubts about Home One lately. I like the protection and crit damage boosts, but Master Plan isn't working out for me. Granted, my AA isn't great (only g8, the rest is maxed), so speed is likely a problem. But I'm finding that even when I do get Master Plan off, it's not a guaranteed win. And if it's been a close battle and I only have a few weakened ships left, then even with Master Plan out, the opponent just kills my ships before they can use it.
On the other hand, I've seen battles where I think I definitely have the upper hand, and I might even have Master Plan already out, but then Tarkin completely demolishes me with Imperial Assault. It's like an instant win in ways that Master Plan often isn't.
But leveling up another capital ship is a huge investment. What do you guys think? Which capital ship of the two do you prefer? Does Executrix have some serious flaws I haven't seen?
