It's ridiculous that I can be going X units while everyone else goes Y units

And despite like 4 people going for the same unit type 2-3 of them get 3 star units with them but somehow I can't even find 1 of the unit i'm looking for that NOBODY ELSE IN THE GAME has any of.

If i'm going nobles or glacials and everyone else is going assassins then offer me freaking glacials or nobles not yordles or sorcerers

bad enough I have to go the entire 2nd stage with 1 item and not a single 2 star unit
