I've been on the other side of this argument, but I agree with Zup now. All it takes is one highly skilled pilot who chooses to wipe the landscape with noob flesh, and you've suddenly got a lot of extremely tainted noobs. Some would move forward like we did, but a lot would quit, and many would continue forward with extreme paranoia. And all would write emails to Zup.
Remember that while many of us sprouted our wings learning from the early mbizzi's, strachan's, and calvin's, the top-end skills are now even better. Those experts got better, and the next in line got extremely good. As tough as it was to be a noob flying with Nov 2012 experts, it's a whole different thing to be a noob flying among Nov 2013 experts. Plus, the number of players is so much greater, and peer pressure to play nice doesn't affect everyone... leading to a few experts out there who aren't so nice. Each of you can probably come up with a name or three straight off. I think unleashing them on Level 3's would be a net detriment to the game.
