Its also not like froyo only went sniper vs these holds (which is the lamest strat to watch imo)
This GF was far from optimal viewer wise, but also definitely not 'some of the worst gameplay' that there could've been. Also I don't think this prevented the game from 'growing' cause as stated in comments above, wG's playstyle was far from optimal even to an untrained eye.
I agree that the grand final definitely wasn't boring and that both teams delivered a good show, but the highlights that the average viewer aren't the little nuances that froyotech showed when trying to break a nearly unbreakable hold. The back and forth team fights, display of amazing mechanical skill and round winning clutches are the highlights that remain in peoples minds and not "oh the timing on this double sacc was really outstanding", so I suppose grand final just lacked those historic moments that people remember for years to come, but it definitely was not a "harmful" game for TF2
