Analysis: Why We Should Buff More Than Nerf
The video discusses something that Dota2 does but Lol does not: they buff weak champions to make them viable, instead of nerfing strong champs.
Whats the difference between buffing the weak and nerfing the strong? When you buff a weak champion, it becomes playable; this gives more options for players to choose from. For example, lets assume jayce is strong right now. Instead of nerfing Jayce, buffing other weak champions will make them playable, and people will play jayce less because they have more options.
What you'll notice from Riot is that each patch leaves 3-4 champions MUCH stronger than the other 110+ champions in the game, which limits the player's choices of what they should play. If more champions were viable, you'd be able to play them and succeed.
Does buffing everyone make the game balanced? Nope, because balance can never be achieved in a game with more than 110 characters that have unique playstyles, build options, and scalings.
