Yes, you are right.
Well, the sync ratio wouldnt be 100%, but if you really want, every Pokemon you catch would be matching with your sync (you dont catch more Pokemon in the same time tho!). I think thats what you mean.
If you could explain why you think this is terrible or OP for the game, it would be nice cuz I cant really understand.
But generally it seems this suggestion is intuitively not liked much by most players. Gotta have to accept that.
