This client is still awful 6 years in

So many client issues over the years you would think this shit would be fixed? No other game has this big of just client problems its sad. Forced to dodge because the client goes grey when you save masteries nice. Click the play button it goes to show my now bullshit wait timer and doesnt even load that just has my screen grey so I have to quit the game LOL. Seriously billions in micro transactions yet you can't even build a client that will work and that your players dont have to worry about. I shouldnt be having to save every mastery in the game because you cant get your shit together with billions of dollars.
