repeating of stars

hey i was just wondering...have u guys noticed that sum actors r repeated in ekta's serials (lucky them)...for eg, da gal who plays mouli in kahin toh hoga, shes in k st pali and also in kyunki as shivangi.

its good to c sum actors repeated though...like rishi frm kahin toh hoga and saumil in kahahi and bajaj n mihir

any comments???
