dont turn it on its head.
If you see someone driving a car with a flat tire, the moral imperative is to tell them they have a flat tire. Keyboard turning isnt just a personal fad - it negatively affects the entire group you play with as it makes you do less DPS and die easier because you are inting your own movement.
This is not an “everyone is valid and loved moment, bud”
Not everyone plays to sweat in a game, “bud”
it’s not about sweating. you drive the car turning with hands not with teeth.
Comparing driving a car with playing a game, nice one 
Let people play a game, a hobby, however they want to play it. This isnt a car where driving it wrong can put others in danger.
I just noticed that when I first log on to my main character - there is a bug → then log on to another character that is in Stormwind - everything works normally → then log back on to the main character and everything works normally… xD
I wonder how much time Blizzard needs to fix this problem 
It keeps happening, struck again after 3 days. Fix this already. The mech suit from siren isle could be a possible cause for this to occur on next game restart.
It does seem to be the Mech that causes the issue.
I found you can also use the console command whilst in the mech to have it turn and respond as quick as if you were on foot- which I imagine isn’t intended, but definitely feels much nicer than the slow and sluggish version we have currently.
(Seriously, we have these models as mounts and they don’t feel this horrid, it makes no sense why this one should be!)
Seems they set the turnspeed once you enter the mech, but something somewhere in the code is failing to reset the turnspeed once you exit the mech or the storm.
theres a few console commands that can break the game
i wont leak the ones i know. it would be a plague on the game if everyone suddenly starts messing with the console commands like common knowledge
i believe blizzard capped the camera distance as an example back in WOTLK
but i could be mistaken
im trying my hardest and i can never get my trust level up
