This is great on paper, but unfortunately no longer translates as well in game terms. With a lot of large based ships released, the 2K-turn simply can't negotiate with these ships who decide to block, meaning some times you're left for a turn with no target. Whilst the B-Wing is still a favourite for me, it needs some titles to breath some new life into it badly.
Also, there is no generic pilot for the ARC-170, rather each pilot brings a unique flavour to the ship which further supports the direction in which you want to build your squad. Want a stress inflicting build? Then Braylen Stramm with a R3-A2 is your pilot. Want incredible action economy and tonnes of movement options? Norra Wexley is the go-to in a build like this.
In terms of price, ARC-170 builds often exceed 30-points but, you always feel like you're gaining a little more value over the B-Wing chassis, just take a look at the movement dial to convince yourself.
