I don't get it... you see it all the time with experts if they are playing a 2nd tier civ like byz or saracens... everyone says it is a really good combo because siege is weak to knights, and monks are good against knights. But both are **** against LC, which are really cheap. This unit combo can be easily countered by only one unit, at trash unit. In addition, this is a very expensive unit combo. So why is it said to be such a good combo?
