The main reason I don't think the Palpatine + 2 Aces archetype is overwhelming, is the number of counters to it. Deny the aces their actions: by blocking with lower PS ships, giving them stress tokens, or using pilots like Carnor Jax. Deal them unavoidable damage: from munitions or crew Vader.
I lost my first two games flying this list: first because of munitions; then from blocking, stress and ions. Granted, I am a mediocre player, placing halfway in my local tournaments. The lesson I learnt was, stay at range 3, and have patience! ![]()
This list is apparently strong against the other two current meta favourites: TLT and swarms. I think both of those archetypes would do well to not just spam one thing, but instead add an element from the rest of the toolbox.
