Hi,
I've used the search and couldn't find a (current) thread for this topic.

Easy-Anti-Cheat has added support for Linux. Technically that would mean users should be able to play the game online with Proton and this EAC option enabled without issues. Is there any plan to roll this out in the future?

+1, especially now that the game is broken on windows for me after today's update but still works fine on linux/proton.
