Maybe we just lose that touch.

I know if I stop for a couple months and come back I don't have the flow and movements are a bit harder, but once you keep playing and knock the rust off it gets easier. I feel when I take a break and come back I get better.

Also, its largely based on who you play and what mods. If you play ABD all day and all you do is snapkick and lift, you are limiting yourself and almost setting a skillcap. Sparrers are always more fluent than strict MP players.
