Ususually a good Focus means wining teamfight. people often forget about the squishy adc ap or other champions in back and it often ends biting them back(for example MF ults your team to doom). Also often teamfight are initiated when your team doesnt know fully the location of enemy which again might easily turn fight badly for you(again as example you may initiate team fight only to get suddenly destroyed by MF ult in bush nearby). Its good to never initiate without beign sure that you wont be suprised and to always focus the enemy that can bring most destruction to your team(it doesnt have to be adc or ap even support can sometimes change the tide of battle ex. lulu)
