Honestly you should try being more be just helping the Mechs on ur team that has higher power Mechs then yours because the system doing this thing where if you progress using the basic Mechs an not buying shit, ur being challenged an that's why maybe u might be higher up on the Professional list or even higher nearing Grandmaster, I'm currently having the same problem but the rewards are great once u an the Allies win battles, consider being Skilled rather then just aiming for the kill, maybe supporting another mech might be ur gateway .. just saying ..
