I think Scuba still had a small chance winning the game by capping the cc with ambush in the end? if he had lvl 1?
Reznov should've won the game more confidently though after getting mid and being on the offensive in Scuba's base, I feel his attacks where too aggressive/overconfident and I foresaw those armies dying due to lack of ecm's or not retreating in time at multiple instances.
Safe play by bunkering/securing mid/sides + migs would probably be better.
Aggressive trading usually works too with such eco difference, but the fact Scuba held on on 1 supply till it got so close in the end is pretty sick.
