Offline Draft playing vs Worldclass when selecting Semi-Pro

Ive started a offline Draft on Semi-Pro just to be sure i win it. I would enjoy professional more but i was afraid to play vs worldclass which could happen and if it goes bad i can lose vs worldclass. So i picked Semi- Pro. All of the Sudden in the final i play vs wordclass. Why the F*k am i playing vs worlclass when i select Semi Pro. Whats the point in having difficulties if you get a random one anyway. I have no idea how someone thought this would be a great idea. Rant over
