yeah... the makers of the game intended this game to be more competitive by having the tiers (from watching the video on youtube), but they missed the boat by not informing us more impatient players well enough so that we wouldn't blow-by the amateur tier, IMHO.
I think there should be a more concerted effort on their part to make sure new-comers are aware that once the "pro" level is made, there is no turning back, and it will cost you to continue, if you are so inclined... but, as I've realized from the get-go, and you'll find posted all over this forum, this is a business, and like any business...
