I was actually thinking of the attack buttons on the "Only keyboard" layout. They are in a position that makes it quite uncomfortable (for me at least) to use. I quickly found out that I way prefer the keyboard and mouse setup, though I do still think that the special attack button on Ctrl could have a better placement. I personally think the control button is too far down to reach naturally, so maybe the middle mouse button (clicking on the scroll wheel) would be a better choice? The same goes for the heal button, which I think could be more optimally placed on F or E.
You're totally right! I use a special WQSD config for AZERTY keyboard to play games (French problems ^^), so I didn't noticed that the Ctrl was sooo far from the other buttons... it's totally irrationnal to have to bend the little finger so much to reach a key, not here to play guitar haha.
Thank you very much for the feedback and the little talk, it was really pleasant to share thoughts with you :)
Have a nice week-end!
