Similar experience here. You missed the biggest turd though, flying!

So cool eh, no more need to walk eh!

What happened was that instead of roaming about with everyone else, you flew everywhere all alone (just point the "fly" in the right direction and wait ... Soo funny).

And to alleviate this they tried to make it so you "had" to walk everywhere first, before getting your "fly", but that just made it worse because now you'd be as slow as before but also alone, everyone else were flying.

Then it became a sort of dungeon-run slot machine, argh.

Vanilla was truly amazing though, what a game...
