I'm looking into Kill team as a way to have some games with my son. What are the easiest factions to run for casual games?
GW kind of sucks at balancing games, how does this game fair? Are there any OP/junk factions I should avoid?
I think you can do pretty well with any of the factions in kill team. The game has a bunch of expansions, but I'd stick with just the core book (or Arena if you're tight on terrain), and go for it!
I think that the only factions you might want to avoid, are ones without any options, like Kroot, or Sisters of Silence.
It's a pretty fun game.
