After 10 lvl better to gunk instead of soak cause a team in this case has the buff of expirience for the killing of enemy hero. In turn, a leading team, on the contrary, has the fine for same thing and for them better go to push.

When they have such a lead they can work on game winning strategies. They are in less pressure to split up since they are unkillable together due to the lead. All they have to do is grab a boss or use an objective to push to core and win.
