After some time. I found a solution.
Basically all I needed to do was grab all my players, and because I am only using one class I use a get all actors of class node. set the view with blend for how ever many it found, then a switch on int with -1 the length of players found.
depending on the number of players just add all the actor locations and divide by how many players are in the game. set the camera actors location to that result and it will always stay in the center of your number of players.
Something of note, Players can still leave the screen unless clamped or you adjust the spring arm length based on distance. Currently trying to figure out how to clamp more than two actors but my main issues has been answered.
