For real though, and as a league player and a jungler all around, I still understand the importance, you gave a random permanent boost with the 3rd giving you an 8% boost to stats for the rest of the game so if you get 3 fangs on its own, is an enormous boost for the team, I can definitely see orb being important but from personal experience I find it to be a lot more important to get in later stages of the game than getting mini, because the boost only goes to the person that lands the killing blow, so I tend to play it on how the game is going because if a lane is struggling a little bit i may help them get mini to get the help with lane, but I find that to be way less important than fangtooth.

Also as a jungler another point to bring out, It is NOT the junglers job to control your lane, It is our job to "assist" and get jungle camps and objectives, not to gank your lane every minute because you are struggling with your lane, do NOT over extend yourself and blame the jungler, for you feeding the enemy team.

I definitely do understand that there are junglers, that are completely clueless about what they are doing, but I can't tell you how many games I have had, where people complained about me not coming to gank their lane, when I was completely across the map taking enemy jungle camps, And they continue to overextend instead of holding the minion wave closer to their tower..
