I have 4 rules
Everybody will argue that in reality this is a complex game with many rules of engagement item customization last hitting and the importance of building for the game you're in rather than building items that serve little purpose for example buying a frozen heart when they have a miss Fortune and no assassins that rely on autos. But for me I have 4 rules!
Rule # 1-Don't die! Rule # 2-Don't die again! Rule # 3-Really you die again :(! Rule # 4-At this point I am already waiting for the game to end so I can happily report you ass for intentionally feeding during laning phase!
Why are these my rules, good question I'll go ahead and tell you! After one death, the enemy laner should be about a level higher than you and now has an advantage over you, at this point you should probably be playing on your side of the river! What about jungle ganks, did you not just fucking hear me? Stay on your side of the fucking river! After 2 deaths, they now have a level maybe even 2 levels ahead, at this point you should be hugging your turret now. After 3 deaths you have successfully fed the enemy and made it hard for anyone else on the map to 1 v 1 them especially if said fed champion is an assassin. Well I almost killed him, well great for you, you also manage to give Riven her ravenous hydra before anybody else has their first complete item, thank you btw. After 4 deaths this champion especially if they are an assassin is now snowballing out of fucking control, you pose no threat to them leaving them free to roam and kill anyone they please. This in turn leaves objectives open for the taking as the constant threat of a fed bitch is making everyone else have to play consciously and defensively there goes our outer turrets, and at the very least dragon and maybe even rift herald. Our jungle is easier to access buffs are be stolen, wards are being placed, and this fed bitch is just laughing everytime we leave our base because they know that we're all about to die. Just focus the fed person, that is an option, but split pushing is out of the question, contesting any objectives is out of the question, the best chance we have at winning is if we can 3 v 1 the fed champion and catch them out of position. Hopefully eventually holding the enemy team off till we have a chance to catch back up. There goes another 20 minutes possibly longer for a game we still might lose lol, point is don't fucking feed the enemy laner, it's okay to lose lane the rest of the team can rally, it's not okay when you feed them.
