You get 15 points per spawn. Could be more but its something.
I dont know if you want to add to much score to it tbh. Right now the players that think ahead and play for the team build the rally points. If you give a massive score to it the players that dont teamplay and think ahead will all build them as well with all the consequences.
As of late its rare to see a game without a rally point. A few weeks ago I could type in chat build a rally point between A and B il do C and A and it was crickets. Right now there already is one right there.
I am thinking the same, you may get some points for each spawn, but building a rally point is time consuming (why i stopped building them)
So i personally think you should get around 100 points for building one.
So is reloading, walking, sitting, shooting a gun, taking a objective you get the point.
Rally point is the most points you can get for building one. Nothing else compares. It is the biggest key to victory to build them and learn where to build them. So building one in a great spot gives you victory which gives you double xp. No you dont get xp for yourself alone you get double xp for the complete team if you rally yourself to victory. In all honestly that shit needs a nerf, super op.
