so this is my problem with the limited time missions, I don't spend money on this game certainly not a couple hundred bucks like it's nothing (to each his own) but with the 24hr time limit they give you is NOT enough to receive the ltm commanders. I have 7 SBs and 56 FACS which I'm told is enough to get at least the first ltm cmd...to date my best ltm was m17... this was after the ltm time mix ups. I think you should be able to finish all the mission in 24hrs with out estimating when it begins and finishes like building 1000 arts for 5days to nail m15 or what ever.
I duno, I've been playing for a year and a half also and figure it's nice that it's not so easy for everyone to gain all the prizes...and duhh why would a company not want to money from big spenders???
