5) I'm pretty sure I've been slapped right in the face by this one. I often go to the dragon or my team's blue/red for the buff when it's icon is on the map, only to find the place empty. I've come to take this as meaning that the map doesn't tell you when the jungle monsters are alive, just that they've respawned. Also, you can't be too focused on going camp to camp all the time. Because if you run into the enemy jungler in a bad spot, chances are you're going to be forced to fight.
Although I've had instances where we ended up gladly ignoring each other for various reasons, like we were both crapped out of health and mana and we didn't want to risk dying, we were too much in a hurry to help an ally in need, or we too focused on getting to buff camp. Those last two were mostly assumptions, but usually we end up starting a fight or chase.
But as I've been conditioned to learn in League, the best counter-jungle one can do is effective warding.
That sound good?
