He's saying it's "unfair" as if the Wiimote is somehow at a disadvantage because of the crappy default scope being even crappier than usual with Wiimote controls. You gotta use a sight regardless to stay competitive. The default scope is too zoomed in and has too much sway to be useful.
The real victims are semi auto users in general since now we're being "taxed" an attachment point to use the Marksman Rifles like semi auto ARs from past CODs.
