I've never flown in an incursion, but I'm thinking about trying it out in the near future. From what I've heard incursion fleets are rather picky about which ships they take, with rather expensive navy or pirate faction ships being preferred.
I don't want to risk a billion or more for trying it out, I'd like to try it in a common T1 battleship first. I haven't had any use for a battleship so far and haven't invested any significant amount of training into any specific race or weapon system at the BS size.
From what I understand so far, missile ships are not in favor and shield tanking is far more common than armor tanking in incursion fleets.
Which battleships are in demand for incursions? Which one should I learn to have a good chance of getting into incursion fleets?
