Why I Will Never Gank for a Feeder
Most people will read the title and get offended, possibly auto down-vote before reading. Allow me to explain myself though.
Bounty values First Blood: 400 gold 1st kill: 300 gold 1st death: 300 gold 2nd kill: 350 gold 2nd death: 275 gold 3rd kill: 408 gold (Killing spree) 3rd death: 220 gold 4th kill: 475 gold (Rampage) 4th death: 176 gold 5th kill: 500 gold (Unstoppable) 5th death: 141 gold 6th kill: 500 gold (Dominating) 6th death: 112 gold 7th kill: 500 gold (Godlike) 7th death: 90 gold 8th kill: 500 gold (Legendary) 8th death: 72 gold 9+ kills: 500 gold (Legendary) 9th death: 58 gold Notes :
That gold values will continue to drop past the 9th death, eventually stopping at 50 gold. Also, with lower killing spree bounty cap and increased bounty gain, there is no additional gold for a shut down beyond the 5th kill. Every 1000 gold earned from minions / monsters reduces the death spree by 1 death. Kills are worth 75% of the base reward during the first 2 minutes of the game, scaling to 100% at 4 minutes. The bonus 100 gold gained from First Blood is not affected by this penalty
Everyone starts at 0. Think of kills as positives and deaths as negatives. If you are in the positive and die, you are brought back to point 0. If you are in the negative and land a kill, you are brought back to point 0.
Also note that earning gold from minions reduces your death spree but doesn't raise your killing spree. That was implemented as a nerf to Proxy Singed who would allow himself to die to point when he was worth less gold than a minion when killed, but farmed so damn much he was fed from farm. Look up "DruidDroid Singed" He is the best Singed player of all time.
If you die 5 straight times to your lane opponent and are 0-5, you have given up a total of 1,112 gold to the other laner. It is actually better for you to not get kills. A teammate that is 4-4 and has traded evenly has given the other team 1200 gold. Once you are behind in kills, it is best to focus on assists and building defense. Why is this? Because if you get a kill and die 5 more times, you just gave up another 1,112 gold, whereas if you just continued to die you would have given up only 382 gold. This makes a huge difference. That is why that guy that goes 17-12-10 is actually a feeder. Chances are he actually gave the other team more gold from killing him than he actually got from 17 kills of killing them. That is why the people that go 10-10 or 8-8 whatever are the worst kind of players. I would take an 0-8-20 teammate over a 10-8-10 teammate any day, because the 10-8-10 teammate fed extremely hard. and contributed to the same amount of kills as the 0-8-20 guy.
So yeah, if you are feeding your lane, I am not going to help you get a kill. Sorry top, if you suck you suck... and if you are getting camped top then that is awesome because I'll be camping bottom and getting our ADC fed and grabbing dragon's while their jungler is spending their time dicking around with you. Best case scenario you are worth only 50 gold to the enemy team and aren't even worth killing anymore, I'm going to let the other team kick your dick in while I camp bot and mid and get our carries fed.
ALSO!!!: Don't be so hard on your feeding teammate. Even if they died 20 straight times to the other laner without getting a single kill or assist they only gave up a total of 1994 gold. That is manageable. The guy that went 10-10 gave up 3000 gold, but you don't call him a feeder?
EDIT: Sorry for the long post. But people are getting the impression I don't gank a fed lane because of bounties... but that is only part of it. I'm just trying to say that there is a point where I consider a lane lost and I put my efforts towards snowballing other lanes. If I spend time helping some dude play catch up, chances are the other jungler will take that opportunity to set my other lanes back as well.
My strategy is that I am willing to sacrifice an already-lost lane for the betterment of the other 2.
