1. Tripping
2. Snake and MK being over powered piles of ****, I refuse to use them because I almost feel like I'm cheating, besides beating someone with Snake or MK people just think "Oh look another Snake/MK won."
3. How much matchups matter, some people are just not meant to win against other characters.
4. The removal of techniques from melee, so that tripping can come in >.>
5. Low hitstun/no combos (few)
6. (I can't only name 5...) Edge guarding is near existent and sweetspotting is done for you, in case you're a noob.
7. All around easiness in comparison to Melee, you can just start off decent, and getting really good wouldn't take nearly as much skill as Melee.
