Men You are forgetting two essential rules about TUS:
1. If You avoid, You dont get points.
2. If You play against ppl that You have sure to win, ok, You ll get points and You ll improve ur rank. But... the system points tus dont allow advantages in this case. Because the noob gamer ll get a lot of points and when He play against noobs again, He ll get only few points.
Example:
PLAYER A Won NOOB -> 40 - 50 points (depends of the noob's rank)
PLAYER A Won OTHER NOOB -> 30 - 40 points
PLAYER A Won MORE ONE NOOB -> 20 - 30 points
PLAYER A Won ME -> 7 - 20 points (hheuahehueahaea)
