So I came into gaming by playing Heroclix in which there are hundreds of current rotation miniatures to build teams with to play skirmish fights.
That being said I like Imperial Assault better as a game. The only thing I've noticed about FFG and it's meta is that (Especially if you listen to podcasts about it) it seems like you only have a chance if you play with one or two teams. I know that X-wing's diversity has improved as we are now in Wave 8, but when I hear things like, "The math for playing Han, IG-88....etc" it discourages me from wanting to even try them, which kind of sucks. I feel like maybe this makes the tournaments slightly more bland than just casual play, but it could be that we only have so few figures yet.
Also like in Heroclix it seems like support pieces can really win games and as of now Imperials have there piece (rightfully so) nerfed and Scum has....none without skirmish upgrade shenanigans.
