Hey, For awhile now I've known that Mineplex is the only server that doesn't have the same knockback mechanics that literally every other 1.8 pvp server has. When you w-tap or s-tap, you reset your sprint allowing you to deal the maximum amount of knockback you could inflict on a player. On Mineplex, you don't need to worry about this because your hits always deal the maximum amount of knockback which is also why players will just straight-line you and combo you. Due to this, I believe that players that get very high cps (Legit or not legit) capitalize off this as a result. Introducing this mechanic back into the game is definitely something we want to do because it's a core Minecraft mechanic that should be present always in 1.8 pvp because it's something that takes skill. I believe that this mechanic doesn't exist on Mineplex currently because of the Champions pvp-system being created before sprinting was added (I'm not 100% sure on this). Champions is an extremely old game so that's why pvp currently is exactly how it is.
