User blog comment:SamthebestBN/Less SP to rank wimp up/@comment-25265892-20140806000153

Well I don't think 186k is a lot of sp to grind out I mean I leveled up my wimps from r5 to r6 in 2 days using 4x sp during double sp weekend sooo I guess you just have to buy the short double sp boost for four nanos during double sp weekend.
