It works very well with Overwatch, but on one of the two games the pointer is missing ... see my post in Problems & Solutions 😉 Thank you for the solution

So, can you tell me what the additional command line argument part does? I am guessing this may solve the problem I was having. I am at work right now so I can't test it, but when I tried playing Heroes of the Storm with 3 terminals it was really buggy and the extra terminals would have issues and would say "too many commands" or something like that in the text box and it wouldn't allow them to ready up. It would work with 2 terminals for the most part, but the extra terminal had to restart the game after every match or two.

Also, has anyone else tested what he is suggesting and had success? When I open the battle.net client and select "Allow multiple instances" and opt for it to close the client when the game launches, it doesn't allow me to open the client from another machine as it says it is already running on the computer. One possibility I just thought of is I may not have selected those settings for each terminal before hand. What I typically have done is run the game, then on the other terminals I have to run the HeroesSwitcher_x64.exe file in the support64 folder.

One last question just to make sure I am doing things right, lol. Do you have a separate folder for each instance of the game? Because I do. So I update the game, then make copies of the game folder for each instance I plan on running. Is that just overkill? I haven't had to do this with World of Warcraft. That one I simply ran the file that opens the game directly, skipping the b.net client. Thanks for posting

Can someone else speak up on this? When I run a game through the Battle.net client, I need to go to my task manager and kill the Blizzard Agent to be able to open it again on another terminal.

Also, can someone comment on whether they are having the "Input limit reached. Please wait to perform more actions." issue when playing something like Star Craft 2 or Heroes of the Storm? I am not sure if it is only happening with my setup or if it is a common problem everyone has. From what I can tell it only happens on terminals 2 and 3, I never get it on Terminal 1. When playing a game or two on the other terminals, once I finish this error stops popping up in the chat log and it won't let me run another game and I have to get out of the game.

You said that To use Battle.net use configure Battle.net-client in a simpler way than you might think. So does it have any effect when playing games fleeing the complex ?

I've tried and found that using the Battle.net-client configuration to play the games is quite fine.
Heroes of the Storm
Hearthstone
Diablo III
StarCraft II

I have successfully tested both games missing using the solution as you give, I think it can run on other devices Dynamons World

I try World of Warcraft and Overwatch on my device and it works.

I used Battle.net in the simplest and easiest way.
