I think we've seen all teams play close to their peaks, with the exception of Spitfire. When (if) it happens, there is not a team out there that will be able to seriously compete. We've seen glimpses of Spitfire's max potential but never the whole thing coming together at once:

• Early stages, we saw the one-man-army dominance of Birdring
• Later stages we saw the dominance of their tank play and coordination with Profit
• In the playoffs, we saw Profit demonstrate the same one-man-army capability as Stage 1 Birdring
• In every stage we saw the incredible consistency of Spitfire's support line

But we never saw all this shit happen together at once. Spitfire has star power in every role, and excellent teamplay at times, but it's never happened all at once. They have won by combining one or two of these elements, and that was enough to beat even the peak performances of other teams. If it all comes together I think we'll see SKT-style dominance of the OWL by our Korean overlords.
