Instead of traditional 2 CP, why not make maps / re-make maps into a “double king of the hill” style map.
When you hold both points you gain percentage capture faster - meaning you almost always have to be on the offense while also having someone poke / flank.
Hard to do in a 5v5 world but could be fun in a 6v6 world where you can send out 4 and leave 2 behind or 3 offense 3 defense etc.
