This mech has been doing well in FP for me as ultra long range support. Dual AMS gives you nice protection against LRMs from the back line. ERLL range and CD gives ERLL with an optimal 750m range and ERPPC has 810. Due to the quirks you can fire very quickly and stay relatively cool. The only problem is lack of sustained damage, but in groups it could be quite potent as an IS answer to clan range.
