Skeeter Mania
Smash Ace
A really subjective thing to be honest. Many of us Smash 4 players actually enjoy watching high level play despite results being somewhat predictable (with the exception of BH5 and MLG especially).National scale is boring because it's always the same people who win.
Consider the fact that besides 5 Sheiks, there were 4 Marios, 3 Ikes, 3 Sonics, 3 Luigis, 2 Rosalumas, 2 Foxes, 2 Diddys, 2 Falcons, 2 MKs, 2 Ryus, 1 DK, 1 Pikachu, 1 Pac-Man, 1 Toon Link, 1 Pit, 1 Roy, 1 ZSS, and 1 Olimar in BH5s Top 32.Not actually a lot of character influence until you go a bit lower in the rankings.
In MLG, we had a Mega Man and a Wario in Top 8. There's always something exciting at this level of play IMO.
