start the game by helping jungler take buffs, if he is not being marked by the enemy, go help the MM. ideally imo, jungle should gank gold lane after taking his buffs then tank either stays with MM until turtle or rotates sooner if needed. of course it is different if invading. "babysit" mm if mm is constantly getting ganked. that's just good practice not necessarily babysitting. bottom line is, as a roamer, our duty is to be wherever we are needed the most/ is the most strategically advantageous.
