Everything in the game has a tradeoff when you decide to back except best casescenario . Let ' s say you are caytlin . You poked the other adc out of lane but no kills on either side . 1 . You look at minimap and game timer , also you consider where was their jungler seen last time , consider enemy mid laner positioning , your hp , your summoner . Basically if i stay next wave do i risk to die ? 2 . You look at your gold . 3 . You look at enemy cs and estimate their gold so what are they coming back withBest case scenario enemy mid is on the map , enemy jungler was top side just seconds ago , my jungler is in my map side river , i have a 10 cs lead and i have 1100 gold . I can push this wave into tower , farm next wave too to get to 1300 for bf and recall , enemy adc will have a pickaxe at best . Worst case scenario No idea where their jungler is , their mid is MIA , i ' m low . I don ' t even consider gold , i GTFO . Always consider is what i ' m potentially gaining worth what i ' m potentially losing ?
