1. Playstyles reflect Melee.E metagame level. Most players seem to play over aggressively with SHFFL approaches. Most players don't play around the limitations and expectations of opponents. Instead they seem to blindly/agressively approach and attempt combos. A few of the best players reflect the Melee.F metagame level (basically the top 5). The few exceptions are: Example 1Example 2Example 3. Winners Finals.
Carroll and Gunblade played in a Brawl like style here. They use more layered attacks, more ground based attacks, and Brawl.G level strategies. Likewise...
Ryoko's Zelda plays very similarly to Brawl Zelda by using Din's Fire in combination with tilts and space smashes, while his Sheik is very much in the Melee style (see here).
