Best AOE medic : Nightingale. Best single target medic : Kal'tsit. I have the 2 Best medic. I need a 5+star guard and you know what I get from headhunting? Another medic. I HAVE 6 GODAM MEDICS NOW. I ask just for 1 godam guard, but doesn't even give me that. If I didn't get spector as my free 5 star in the beginning I wouldn't even have a good guard operator. Seriously the system is so trash and so is the balance. 1 level is so easy and the next level is unable to clear unless you look up videos
