Watching EU v NA was one of the best TF2 spectator experience I had in this game, it is something we have only seen once on LAN and if it happens again it would be amazing for TF2.
It won't grow TF2 into eSport, it won't suddenly give us 5000 viewers for every invite/prem match but it would be a fantastic event for us to sit there and enjoy for a weekend and be even better for the players involved.
Anyone who thinks we should as a community think of clever ways to invest in TF2's future is deluding themselves, we're not an eSport, the game creators don't want to back the competitive side financially at all. TF2 will die eventually, it won't become a major eSport ever so lets give us some great memories to enjoy this game whilst it is still alive.
