Can someone explain this to me??

It just happens. I don't want to choose sides or start an argument but in my own personal experience survivors are more likely to complain or trash talk after the game. I'm a survivor main so that means that I too have been trash-talked by other players on my own assigned "team". It doesn't happen often but it's happened a few times, usually to question my style of play and scold me for what they perceived as "not doing enough" or playing the way that they wanted me to play. I don't hide, I don't avoid the action. I'm just careful and try to avoid direct confrontations with the killer where possible. A lot of teams are aggro and don't like this. They don't always see me much during the game so they just jump to the conclusion that I just stood in a corner and cowered, waiting for the hatch (which is something I've ALSO had to deal with other survivors doing. It sucks).

In short, don't worry about it. There will always be people who will find something to complain about, even if you played well and contributed just fine. You might get a killer trash-talking you for it sometime too, but - and again, this is my own anecdotal experience - survivors are more likely to whine. Many of them just want everyone to rush gens, abuse flashlights, do loops around the killer, and teabag at the exit. Not ALL of them, certainly. I don't play like that at all, plenty of people here don't. But there are those who do, and my understanding is that it gets worse around the red ranks. Some people just like to complain when something doesn't go the way they want it to.

EDIT: By the way, don't let anyone intimidate or guilt you into changing your build or playing differently. The game is for everyone, including you.

Well they are saying that because your build suggests that you hid in a corner the whole game. Its not your fault bro don't worry about it. Sone people just take these things too seriously

That says it all. I've noticed that a lot of my fellow survivors get bent out of shape with stealth play. They like to assume that you're not actually participating and whine at you because "you were off hiding all game while I did 3 of the gens myself". In other words, they like to aggro and expect everyone else to do the same.

As I and others have said, play how you like and don't feel pressured to change your perks. I'm a more stealthy player and I like it that way, I don't care if my teammates don't approve. I do gens, hook rescues and healing, I just don't run around all willy nilly and I don't like the looping game. That's my prerogative. As long as you're playing and not deliberately breaking any rules, you're fine.

Why does UE have a bad reputation?

I use UE myself, unless I've got it swapped for Dwight's perk that speeds up the actions of those nearby (can't recall the name of it). Beyond that I always have Bond, which allows me to see my fellow teammates from a decent distance, and the combination of Kindred and Dark Sense, which give me occasional updates on the killer's actions and whereabouts. This is a good stealth build but the treadeoff for more careful, evasive gameplay is that I have NO perks or advantages whatsoever to help me when I do get caught. Additionally survivors get more points by putting themselves in danger, you can do several gens by yourself AND escape but still make less points than someone who spent the whole game running and recovering from interactions with the killer. So basically I've got probably a 50/50 win/loss rate, maybe a little better, and the development of my survivors is slower that it is for a lot of other people. But I don't care, I enjoy playing the game in the style that I do.

That's what I figured: Evasion = cowardice. I could see the complaint if it were leveled at the type of players who legit DON'T do hooks, DO sit around in lockers and bushes all game, etc. I don't think that anyone appreciates that type of teammate. But I do wonder about the "hiding as soon as they hear the heartbeat" thing. Do people actually have a problem with that? No one in any of the games I've played has ever just stood around (or attempted to bumrush the killer) when they get close, everyone scatters and either runs or hides until the threat is gone. Isn't survival the point of survivors?

I know you're not the one making the accusation, I'm just curious if this is a common sentiment.

They're the toxic one, but a lot of people instantly dislike those who run urban. It's really not a good perk, so I'd recommend dropping it from your build. Then you won't have this happen, or at least not often anymore.
