This might sound like i haven't read the battery info apple supplies, I have, What happens is, I have 8 cycles right? When I play games like League Of Legends, I keep it plugged in to stop cycles.. yet the maximum charge still goes down. I am looking in my battery info and every time i look it shoots down by 10. Please help? I don't know what to do. i have a macbook pro mid 2012 OS X 10.9.4
Addition Info: I also just web surfing plugged in, I still loose charge every time i look it goes down between 1-30 i thought when you kept it plugged it doesn't mess with the battery? I don't know! help
The power system is designed to draw power from both the wall outlet and the battery under high-load conditions. Just about any game with graphics creates a high-load condition. What you see is normal.
I have fixed my problem, I calibrated my battery and it no longer looses maximum charge!
New batteries should not need to be calibrated. My guess is Allan's answer is correct and the issue will return.
Thanks,

It seems after I calibrated it, it went up in maximum charge... And it no longer goes dow. When it's charged.
Calibration is not necessary and is only a temporary fix for your model. Read this directly from Apple regarding calibration:
