TongFu wouldnt have won though, it was a legit tactic.. as legit as Alliance is split pushing, as legit as Kotl + pl, or a 100 min game by DK.
Of course it shouldnt be played everyone map, would become really boring and I'd say not everyone would be able to handle this.
EU dota > asian teams. It's also mostly boring to watch asians play plus there are 9 of 16 teams who are asian, and only 2 NA teams... would find it fair if its 1/3 of each, 5 EU, 5 NA, 5 Asian teams + 1 wildcard =)
