Well for one you always start in the forest, you don't go straight to your lane, around where the lizard is....
Jungling is much more important there, lots of buffs, dragon is like the TT's baron, gives everyone a buff, slow pokes get the speed buff, dps get the lizard and attack speed buff... yeah.
Oh, and of course, ganks are a must, and since everyones gonan get ganked, wards are a must as well
