Solar. Why? Because Hammer throwing Titan Self resing warlock and golden gun hunter I have seen a golden gun take out a Titan bubble in 2 hits a nova bombing warlock in 3 hits and a void bow hunter well I don't know yet and the hammer throwing Titan will just jump and throw jump and throw jump and throw he would be unstoppable and the self resing warlock would just throw fire bolt grenades at everyone and make them burn a long time
