Hello mohlin! Your English is not that bad, so that is not a problem and you would not be the only father that plays with us. Most of us are 30+ years old.
I prefer to have reliable people to play with and discord makes communication easier for all of us. I understand that sometimes people can't be online or that they have to mute discord, but at least when we have an important event (Raids/Sieges) I would prefer to have everyone on discord, even if their microphone is muted.
What class are you thinking of playing?
