What make them more common is the fact that there are 12 people racing at one time. Thats another problem I see aswell, ist that there are too many people on the track at one time. Getting hit with a Spiny Shell in older games would only cause you to lose 1 or 2 places. Get hit with it now, and you go from 1st to 8th, or worse.
The oppisite could be said with Bullet Bill. Getting him would allow you to go from 12 to 3, which seems highly overpowered in my opinion.
