I like the idea of there being two control points instead of one, but at the same time I feel that the 2nd point gives the winning team too much of an advantage after they had capture the first one. I mean, being able to shave off a whole minute on once's timer is done right insane considering the fact that not only does the losing team has less time to recapture the point, they also have to hold the point a lot longer. Which isn't necessarily a bad thing, but I feel rather discouraged when me and my team were unlucky enough to capture the 2nd point in time, cause it's basically an guaranteed win for the team that was able to capture both points.
What I would like to see if possible is to make it so that if a team is successful at capturing both control points is that their timer goes down twice as fast. Not only will this give the team that was unable to capture both control points a bit more of a fighting chance, it will also give the 2nd point a bit more of an propose cause it could stay unlocked throughout the whole match. However, if you go along with this idea you may want to extend the KOTH timer to 6 minutes instead of the default 3 cause matches will feel way too short if you didn't in my opinion.
