Why are handicaps such a huge part of this so-called "competitive" game?
I guess the overall argument here is that in a competitive game you want skill to be maximally responsible for the game's outcome. As it stands right now, because of the things I have listed below, skill influence on game outcomes has been reduced, which is completely inimical to balancing a competitive game.
SHUTDOWN GOLD - It scales too fast, and maximum values are capped too high. For example, if I kill you twice I am worth 450 gold and I got 570 gold for killing you those 2 times. If you kill me after getting a gank, we are back to even despite me playing better than you. Skill should most influence the outcome of a game; don't reduce skill influence by adding handicaps.
SHUTDOWN EXPERIENCE - This exists in its effects, but not by name; Riot doesn't claim that there is something called "shutdown xp." In any case, if you kill someone you get 50% of the experience required for them to level up, plus 7% for each level you're behind. At lvl 7 you require 3200 xp to level up, at level 5 you require 1700 xp to level up. If you do the math I just laid out for you, you will see that the level 5 - if he kills you with his jungler - will recieve 2100ish xp, which is enough to level him/her up and then some. Again, remove handicaps, because in a competitive game we want skill to most influence the game outcome; handicaps are inimical to this.
SHUTDOWN DEATH TIMERS - Once again, this is something that exists in every form except for by name. The gist of shutdown death timers is the fact that death timers vary with level, and not by time passed. The higher your level, the longer you wait when you die. This exacerbates the effects of shutdown xp and gold, because not only do you lose most of your lead from those 2 factors, the prolonged death timers give your opponent even more room to catch up by allowing them to deny you farm, while also providing them with the opportunity to farm for themselves. Again, why are handicaps in this game? Don't suggest that this game is competitive until you remove handicaps.
