Understood, I don't know much about the community of Warhammer since I've never played any of the games. But I like to think that not everyone is bad, just don't hang around the bad ones too long and keep adding, you'll eventually find someone who you can agree with. Or is there perhaps a Warhammer Forum that you can post for possible team mates on? It would be better tailored for what you're looking for.

I tried, but nobody had responded on that sadly

Well depending on how active the games community is, is how long it could take. A bigger community will require less effort, a smaller community will require longer searches, so I guess all you can do now is keep on searching. I imagine different people play everyday, so you'll perhaps have bad days where a lot of toxic players are on and good days, such as the weekends for the possibility of some good players. It's just a waiting game afraid, waiting and keeping up the attention that you're looking for friends to play this game with you.
