>>273914382008: Metagross (3/4)
2009: Ludicolo (3/4)
2010: Groudon (6/8)
2011: Thundurus (7/8)
2012: Cresselia (7/8)
2013: Landorus if counting both formes (4/8)
if not: 9-way split between Landorus, Cresselia, Thundurus, Conkeldurr, Heatran, Amoonguss, Tyrannitar, Latios, Jellicent (3/8)
2014: Garchomp + Mega Mawile (5/8)
2015: Landorus-T (All fucking 8 teams)
So in terms of singular Pokemon being over dominant on the meta, 2013 seems to be the best year for VGC, with 2014 not too far behind. 2015 (and probably 2016, we'll see in a few weeks, but can't imagine more than one team not having groudon) is by far the worst, purely going off top 8.
