To junglers, from a solo laner

If you, as a jungler, want to go gank an ally midlaner/toplaner, you should actually consider your ally's position instead of only looking at the enemy's.

If your ally is currently farming under tower behind a massive wave creep, don't expect to get help killing the enemy at the other end of the lane, especially if your laner dosen't have major mobility. Pinging us because you dove under turret in hopes of killing the enemy by yourself won't change the fact that your ally can't go through 2 and a half waves of minions and teleport by your side instantly to help you.

If the enemy is just behind his own wave, you might have a chance to get help from your laner, depending on his champion. But if the opponent is waiting for the next wave in the middle of the lane, its nearly impossible for your ally to go through the creep block to the other side of the lane to catch up the fleeing enemy.
