I Don't Understand Why Mobafire Gets Such a Bad Rep

So I have been only playing League of Legends for about a year or so, I'm not super high elo or anything just your average silver/gold type of player. Everytime I watch streamers such as Nightblue, Trick, pro players, etc they always rip Mobafire whenever the topic comes up. I understand that Mobafire can be used in a similar fashion as Wikipedia since anyone can post builds and stuff on it, but isn't that the point of these types of websites? Mobafire is a great place for people like me to go and look at theory builds, cheesy builds, fun builds, and even serious builds when I need one. The streamers and YouTubers usually tell people not to go to Mobafire because you shouldn't build the exact same every game and instead link other sites, sites that will usually offer the exact same builds and tips as Mobafire but on a smaller scale. Anyone with a brain that has played league of legends for more than a month knows that they shouldn't build the exact same every game and to change up their build based on the enemy team comp, who is strong/fed, etc, and most of the time the high voted/popular builds on Mobafire are made by Diamond and up summoners and are very in depth on what items you should purchase in certain situations, along with crucial tips on how to play every stage of the game based on what is happening. Some of the tips in these guides are ones I have heard from pros, champion guide videos, and other sources that are reliable according to the entertainers, so it doesn't make much sense to rip only these sites when videos can be just as misleading. I enjoy most of the entertainers I listed and use their tips too, but it is highly probable that combining their tips with tips from other people will make my play better than if I was just following their advice, because no one person knows everything about every matchup and comp in the game. So I believe Mobafire is a great website that is accomplishing exactly what it is supposed to, to be a database of information relevant to LoL that is easy to navigate and provides builds and guides for any type of player (yes even toxic and troll ones).

Any feedback is appreciated!
