So i was playing today and i was using my 137 set which consists of a tier 2 head and tier 3 body & arms yet i was only getting the tier 2 15% exp bonus? :-\
Cuz head was t2, if u have a head that is t1 or t2 dont matter what tier other parts are(body and arm) u will still get the head bonus,(0% in t1 or 15% t2)
