We've played through the Core Set campaign once and played through all the skirmish missions a couple times.
Skirmish with Core and Wave 1 seemed fairly well-designed and balance.
But now with Wave 2 +Twin Shadows on us, followed closely by Wave 3, Wave 4 and then Wave 5 with another box, there's certainly a feeling of a lot of stuff.
I've posted this similar sentiment with X-Wing. But Imperial Assault, unlike X-Wing, allows cross-faction. Plus the majority of command cards applies to pretty much everyone.
For Imperial Assault, does anyone else feel overwhelmed or an impending overwhelming? Is Skirmish going to be balanced? Is the meta going to shift every 2 months with each Wave?
