why is factions so toxic now?

Well, a lot of factions servers are based off the Pay to Win system, wherein many players use their IRL money to buy things to make them powerful ingame, and the people that don't have the money to buy it just keep getting killed, over and over, and people don't stick around when that happens. The people that do stick around are mainly kids whose parents buy them everything they want, no matter the price, and they often get away with everything, so they DDOS and DOX people that get on their nerves.

because factions is a crappy gamemode that is getting boreing and out played

People who get power enjoy the feeling of domination, so they go after small bases and destroy them to prove their superiority.

I remember something like that happening to me, where I had some underground base and then two days later people started launching TNT at me. Bear in mind that this was at around BEDROCK level.

Its a competitive game. And especially when many people spend money they will sweat

Because it is really competitive and people who play it are mostly salty children.

not all factions are toxic? I don't know what server you're talking about. though salt in main factor

When I was playing minecraft there were no people like this.. I think this game is just getting to the past.

eula is prohibiting P2W..
what are u talking about?
If u see a server using some P2W stuff report it and it will be closed ASAP.

Just kids are playin factions/not for all just in my option...
