A while ago I used to be big into D3. I had played on my Mac laptop (of 2008 vintage) up till a point where I was forced due to my laptop's lack of power to play on my significantly more powerful gaming PC.
I used to play on that PC with D3 a ton, until I bought a Logitech Keyboard (specifically the G510) with advanced macro keys and a LCD screen for displaying game info.
Soon after getting this keyboard, I had heard people were getting banned from D3 for having the keyboard attached to their system, not even using the macro keys, and I haven't gone near D3 since.
I know Blizzard supports this keyboard with WoW and maybe SC2 (unsure on this one), so why would they be banning for having a piece of gaming hardware attached to their system?
I use the Macro Keys for automation outside of games (I got it mainly for the LCD screen) and I've used the macro keys on other games when I need a single keystroke accessible under my pinky (i.e. calling for medic while moving, "dropping the intel" or using voice chat in TF2)
So, the question I have is this: Is it "safe" to run D3 with a Logitech gaming keyboard (G510) that has macro capabilities, even if the macro keys are not being used or if they're being used only for single keystrokes?
