Not sure what to tell you. But honestly was it your team or squads fault? First off you can not win every round. If you do then I would dare to say there is something hinky with one or two of your team members. I mean come on. Given the numbers you simply can not. Everyonesle on xbox is not dumb.
Second did you really help your squad. Or did you cost them more tickets by running in blindy. Did u hold up so they could spawn on you. Only u know the awnser. Of course in joining random squads I have heard everything from they are cheating to Only level 50 should have the abilility to kill me. I simply love the level 50 remark.
Your team lost it happens, move on. Learn give others time to learn. Bossing helps no one unless they ask you for it.
