I played yesterday too and i'm not completly happy with the changes made according to the stamina.
It reduced a bit the fun on the gameplay for me. 
Sometimes i need to hop over obstacles and everytime now i loose stamina with every hop i do.
The problem is, that it doesn't recover fast enough. It felt like i had to wait forever to be able to run again.
The basic idea is good but there should be made a difference between a normal hopping and the bunnyhoppers.

Only players which hop repeatly (more than 2 times) shouldn't be able to run directly after that.
All others shouldn't be recognized by the script, because that wouldn't count as bunnyhopping for me.
As i said sometimes i (and i think other players too) want to jump over obstacles and i don't see a reason to punish them for that by reducing the stamina, if they just hop once or two times.
Jumping over a wall doesn't always work on the first try, so you hop again. Another example, you try to get up on a high hill, so you need to hop too on some point to get up.
