Power creep is a "soft rotation" where the overall pool of options keeps growing but the "viable" pool shrinks when new cards are released with increased power levels. in x-wing the developers attempt to keep the miniatures viable with new cards but the cards themselves may as well be disposable or on rotation.
overall I think this is great! The cool ships get to play and the old cards can just collect dust and maybe something comes along that makes them relevant.
however I do wish table clutter and stacks of upgrades were not required to fly old ships like an a-wing. maybe we will see more combo upgrade cards? but pobody's nerfect
how do you guys feel about this direction. I don't see a need to refresh the whole line at any point in the future. aside from wanting objective play in official events everything is fine.
