im not sure if you will consider me good but i can do my part.if my allies are ok and can manage i upgrade to super units first.If i'm playing cutter i usally get anit-air/vech + eletps since ODSTs can be spammed by eletps and that ODST drop power thing.(i dont play covies much).And what i do is get Counters+super units depending on what are the enemy types.
