Best way to give feedback?
I wasn’t a part of the previous betas, but I can expect feedback can be given both here on the forum and in-game through bug reports – hopefully someone from a past beta can clarify here.
For actual feedback on how something can be improved (as opposed to a simple bug), a good format for a feedback post can be found here.
These forums (make sure to post in the appropriate sub-forum) are the best for getting your voice heard. Devs go to other sites like Reddit too. They also watch us in game to see how things play out.
There was no feedback option ingame
It depends a bit on the type of feedback.
If it is a simple bug, I would recommend a bugreport in game.
As it is more broader bout a mechanic or bout how you like the atmosphere, I would recommend to do it in here (this section of the forum). Make sure you start your thread with a recognisable line. It would be nice if e.g. Gaile would approve of one (I know she is busy in Cologne though). But I think if we all use : “BWE1 FEEDBACK”, it would be very convinient for everyone.
Arise, opressed of Tyria!
