It already was a draw, just a really really bad one where you could get multiple "entries" by opening multiple browser windows or you could pay to have someone in person give you a "top 10% entry" or whatever.
This simplifies it - one person, one entry.
As someone else pointed out, the number of tags (ie opportunity) hasn't changed.
This hasn't been an OTC system for years. OTC is like eastern whitetail (or resident ID) - walk up to the counter (or online) and buy your tag. "Getting a random spot in line" is just a draw with more chaos
