World of Warcraft

I've been dancing around the idea of getting a SteamDeck and had a couple of questions for anyone running WoW on it. I'm not planning on mythic raiding or anything similar to it, would mostly like to quest, ach hunt, similar "chill" stuff but would definitely like to try and see how playable a dungeon or LFR would be.

It's hard to judge how smooth the game is by YT videos, but I'm very interested in hearing how smooth the game feels when you, for instance, lock the FPS and refresh rate to 40hz? As it seems, at least from what I've seen on YT, that there's a lot of fluctuation in FPS so my line of thought was that locking the fps/refresh to a bit lower value might make things smoother, but please correct me if my assumption is wrong here.

For classes that have pets, any problems with limited number of buttons on the SD, as in any issues with binding some basic pet commands to buttons available on the SD.

Any issues with device getting possibly too hot to play comfortably? I've seen temps reach 70-80C in some of the YT videos.

I've seen some random posts that some addons do not work? Is there a way of mass updating addons other than downloading every single one each time there is an update? Curseforge in AUR is no longer maintained unfortunately.

Please feel free to mention any positive / negative experiences you've had with playing WoW on the SteamDeck. Thank you!
