As a tank jungle main this is my rule of thumb:
For ganks: Was it successful?
Yes. (burnt their sums without team mate burning sums) No kill. Tax 3 minions
Yes. (a Kill was secured regardless of sums by ME!). No tax, if the lane is already shoving towards enemy tower I will use AOE to speed up the push without taxing.
Yes. (a kill was secured regardless of sums by my team mates) I will tax 3 minions or a cannon. I will then proceed as above in regards to shoving.
Yes. (a countergank or save. I didn't get you any money however I deprived the enemy of money and possibly wasted their sums by keeping you alive). I will shove the wave and tell you to B. If you're low enough to need saving you shouldn't be in lane. And this way the XP and gold doesn't go to waste by dying to tower.
If they tell me to leave I will leave. Simple. Their lane their rules. But this goes both ways but more on that later
No (no sums were burnt, no kill). No tax.
**Because I've already soaked some XP from the minions that died during my visit. I've already taxed your lane without even trying.
**
For other situations it's generally me just shoving a wave to soak XP rather than gold and I will ask the laner if it's K to do so.
Team mate dies, enemy goes B and I shove the wave.
Enemy dies, team mate goes B and I shove the wave.
Both laners B I shove.
I hold lane
ect.
In many cases the team mate either owes me a little tax or wouldn't of been there to get it in the first place.
Now onto how it works both ways.
Buffs. One of the most irritating things a jungler can experience is a self righteous laner who thinks that Blue or Red is their bloody birthright.
Just as the minions in your lane are YOURS. The buffs and these camps are MINE.
If you're fed, struggling but playing well/not tilted or are a champion who would benefit greatly (Champs charging
) I will likely offer it to you if I myself don't need it.
If individuals ask for it. Not demanding or strolling over while I'm doing it expecting to get it. I will oblige as to encourage good behaviour and reward those who respect that it isn't "theirs".
However if you're fed but cocky (likely to throw your lead), behind and tilted or a vulnerable laner (having a buff in lane makes you a more valuable target) I will deny you the buff as it will likely time out rather than be transferred to the enemy.
But those who ping "on my way" without asking/being offered, say "grabbing red" or simply try to take the camp by force will be met with the almighty
. By giving my buff away I am losing XP, gold and stats that would help me clear and gank. The only thing many think about blue is "MANA!!!!!!!!".
These buffs are for the jungler to give, not for a laner to take.
Just as minions are a laners to give, not the jungler to just stroll by and take.
It works both ways and I dare say it happens far more with buffs than it does with minions (but that's likely because I'm the guy always jungling ;) )
