Are all killers equal in DBD (in soloQ)?

Yes, indeed, facing a good Pig and a good Nurse is the same level of difficulty. Please, I hear nonsense, but this is too much...
The Pig is an M1 killer, so is the Trapper, whether you like it or not, it's a solid argument.



Why do killers tryhard all the time?

Complaining about tunneling has become a trend. So yes, with 5 generators remaining, it might be a bit unfair, in public matches we are not in a competition, admittedly. However, the definition of tunneling doesn't change when it suits us. The killer is trying to win their game.
On the other hand, gen rushing is a misconception. The reason why you feel like some teams are more effective than others is because... some teams are more effective than others. Plain and simple. The survivor's goal is to complete generators. You have perks to counter that, and they have perks to counter yours. Moreover, the best perks in the game (in my opinion) are protection and looping perks.



How can I improve in DBD?

Finally, a sensible question! We don't all have the same level. Depending on the games, I receive compliments, but sometimes I totally miss my game. Don't listen to those who come crying because you didn't carry them, it happens, it's human.
Watch streams of very good loopers/killers: Ayrun, TheJRM... or very good theorists: tru3ta1ent.
Or even competitive channels, or competitors (The most famous: Zaka, Knightlight, DBD League, or my friends from L Tournament...)
If you have the opportunity, do 1v1s, and if you have the courage, do scrims. I myself don't do enough of them, which prevents me from being constant.



What should I do at the end of a game?

Your game may not have been that good, perhaps, but think of a gg addressed to your teammates and the killer. Be kind, and if the killer is nice even in the chat, give them a +rep. It's important.



Is P100 synonymous with a good level?

No. Stop believing that a P100 will save you in the corner of the map against a facecamping Bubba, with no pallets, 3000 leagues away from the exit gates. DBD is not magic, it's strategy. I digress but... prestige 100 means nothing, except 'played a lot'.
The best players are competitive players, who evolve in scrims and 1v1s and who do not necessarily have a prestige 100. But facing them, you'll have a hard time (we learn the hard way).



Why are the French so detestable?

Because they live in Paris? Not all French people and not all Russians are equal. But there is a concentration of nastiness. But since every person is different, if you insult based on origins, you're not honoring your country either. I know you're not very good at DBD, but you're not better at geopolitics.


Do you understand all this ? Then <3 to you and above all I wish you the best, my little Myers!
