I click about 10 times per second and the game is putting a limit on how much I can click. It does this with a macro as well. It's just like everything before Minecraft 1.7.
What I expected to happen was that I'd constantly click like I did in 1.7.
What actually happened was there is now a delay to my clicks.
Steps to Reproduce:
1. Install an autoclicker or use a macro mouse
2. Attempt to click around 10-20 clicks per second,
3. Watch as the game restricts you from clicking.
Invalid.
Minecraft being compatbile with any 3rd party clicking robot is not a feature.
