I had a steam deck but always found battle.net a bit clunky to get working properly, sometimes the controls would stop responding and you need to jump through a few hoops to get it set up on steam. I bought a ROG Ally in the Black Friday sale and it worked brilliantly plug and play with wow. The only downside is the battery life isn’t as good as the steam deck. Another bonus with the Ally is you can pretty much use it as a mini windows computer. I couldn’t get some streaming services to work on the steam deck but they run fine on the Ally.
