I will see you in the normal games, sir.
That's where you really should be. I thought the same way that I think you are..I was stuck between annihilating in beginner and struggling from time to time in intermediate. The thing I've noticed is, and there is no offense meant by this, but playing against real people is actually a lot easier than bots. Bots don't make human error, people do.
I was so scared to play my first game against real people I actually apologized to my team before hand. It only took me a few minutes for me to discover this was not necessary at all since I was doing far better than they were. I went +10 my first match. It wasn't nearly as difficult as the intermediate bots....

If you'd like to make the jump with a friend on your side, feel free to add me
