Is this formation viable? 3-2-2-1-2

[talisman]

I tried this tactic many times before, and i realise that use 1 tactic for all matches is bad. This tactic is not strong enough to win another strong midfielder tactics, such as 4-1-3n-2, 3n-1-4-2, 4-1-4-1, 3n-5-2, 4-1-2-1-2 Narrow Diamond...You'll lose possession and make least shots. Especially, when you lost from some corner kicks or free kicks, it's too hard too find goals against them.

Used this formation this evening against a 3N-1-4-1-1 (Cross?) formation. Was a struggle all way through but as the opposition players were performing poorly (one 4 and three 5s), eventually got through 3-0.
