Would really depend on how much longer your time would add to the raid but either way the points you would get would be really small in 3 + 1's unless you make the overloads. (So No tekton/vang/mutta scouts cause they drop overloads.) Your best bet is to try and join masses or host raids in W365 with a main and just take your pure in.
I could take you on 1 + 1 raids but I dont think you would get any amount of significant points for it to be worth it. Im thinking like 3-5k points.
