After seeing the unboxing videos of wave 2 (thanks Team Convenant, love ya work), and reading some of the hype/plans on these forums, I'm thinking the hardest hit by these new figs is the stanard Tie fighter.
With a host of new upgrades, a Firespray that could potential 50-60% of your squad (assuming it stays at 100 points) and the tie interceptors looking as deadly as we hoped they'd be, it's looking like the focus will shift to less (but better) ships, and away from swarm. With this in mind, do you tihnk the standard Tie is already on it's way to becoming redundant/superceeded.
I know swarm will always be an option in some form or another, but will it be dropping off drastically in favour of 4-6 ship builds that feature little or no Ties (i know 6 borders on swarm, but once rebels can go to 5 ships comfortably, it's probably not so much anymore).
