I hate how competitive this game has become

Its kind of the nature of things.

Running many RPG games and groups I find that players tend to gravitate toward one major viewpoint which can be loosely cut down the middle of thematic gamers and power gamers. Its not completely black and white but generally.

Thematic gamers tend to appreciate the theme over the mechanics while power gamers like to game the mechanics to the upmost regardless of the theme.

You can usually see which mindset people gravitate toward in their opinions about how the game should work and what they appreciate about the game. I also find that online PvP environments tend to favor the power gamer more than the thematic gamer, as the competitive nature tends to turn a lot of thematic gamers off.

I should say that both groups are capable of getting way to seriously into their roles, thematic gamers who go over the top tend to be incredibly tedious being very difficult to work around things that are broken in order to reach a good balance. While power gamers who go over the top tend to be rather arrogant poor winners and sore losers demanding purely mechanical fixes even when completely immersion breaking.

A balance between the two is what's necessary.

I think streamers make up a special case, as some are very good but many are just regular people trying to monetize their hobby. There was a day when to have viewers you had to be talented or capable to some extent. Now days all you need is a camera, which means there are a lot of people in front of cameras who just shouldn't be there and their terrible personalities and attitudes toward gaming and life in general are on show for all.
