A lot of the time, when you PVP in vanilla Minecraft, combos aren't really important and just diminishes your opponents health. But in CubeCraft and especially games like SkyWars where there is void or Survival Games with the border, if you get a combo, you have won a fight. Even in full diamond armor and you fighting a poor guy who just found some chainmail boots, he can legit just throw you off the map and still have 8 hearts. Why?! I have lost too many Skywars games to a guy who comboed me off the map. And during a combo you can't even get out of it because the guy has you 5 blocks away and just knocked you off your spawn island. I feel like nerfing combos (and knockback maybe?)would make the pvp experience more fair and fun to play.
