Yes.... The better you get, as in moving through the Tiers, the game gets harder to play too. Don't get discouraged though, the game does get easier, I'm still waiting for it to get easy, but that what gets me back too....lol
Start playing games with higher Tier people and start getting use to thier conditions, so when you get promoted it won't be a shock to the system.
Good Luck and remember to have fun
