Coman is very simple for doubles, everyone serves from the same side they served from during the set. The first person serves once from the deuce court and then everyone else serves twice starting from the ad court.
It actually makes more sense for doubles than the old way.
In singles it may be a little more confusing ... but it is still less confusing than sometimes having to serve 1 point then switch sides before serving your next point.
Even in singles,after the first point, both people serve two points then switch sides and repeat
