A church full of apostles or prophets would be a very deficient church. Each gift is important - this is exactly was Paul is saying in ch. I see the listing as most probably according to church structure. The problem with the Corinthian church is not just the gifts but the USE of these gifts. People were misusing their gifts and pushing themselves, building themselves up.
Gifts are of no value unless they are properly used, for the benefit of the church.
The charge is to habitually seek spirituality - especially that you may prophesy.
