What IS a shade account in your opinion, and what's the problem with it?
In my opinion, a shade account is (someone correct me if I'm wrong):
1. An additional account that is logged in simultaneously with a person's main account, but logged into another country, to find out locations and positions of missions/goons/people on the enemy side.
2. An additional account that is logged in simultaneously with a person's main account, but logged into another country, and is killed repeatedly by the main account to increase score / acquire perks.
My problem with it is inherently obvious.
