Balancing Towards Closer Games - fun to spectate but is it fun to play?

It seems with every patch league of legends games get closer and closer.

With closer games, games that would have snowballed a victory in the past due to taking positive trades 3-4 times in a row can now be flipped after taking 1 bad trade later on. Thus continued good play is rewarded, makes sense.

I know I find close games super fun to spectate when I'm watching pro play. One of my favorite games of this year below was Game 3 of KT vs IG which was an awesome series and I would recommend. https://www.youtube.com/watch?v=pJqaoHlN5Ag I don't think the game could have been any closer 1 or 2 AA off a different outcome.

My question is do people find close games fun to play and should all games be close? When games are on a knifes edge it can be extremely rewarding but also extremely frustrating depending on if you are the victor or the defeated. Creating a higher stress leveled environment than before. (I know its a game and stress level varies per player but I'm happy to assume a closer game would yield a net higher stress for most/all players even if that stress level is still negligible)

What are peoples opinions on this?
