You can use a pet that's 19 levels higher than you if he's 20 he won't respond to any commands you tell him to.
And when you are 10 levels lower, he's speed will be at half, he's speed will grow along when you level up.
We all needed changed, it was already at 1 AM and it was late, but i could still wake up and go to work but 2 AM it's just insane.
It's too much we can't stay everyday till 2 AM without affecting us.
