I'm seeing a lot of old posts in this thread about slowfall being broken for characters that don't have a native slowfall ability. Perhaps slowfall should be off by default? or check to see if you have the ability and/or item that allows you to use it? Because it's still broken! =)
Also, for MoP rares, why can't we have that checked until we are 90? I'm a hunter and I can easily kill most MoP rares with a good tank pet at lvl 87, so why miss out on potentially good gear upgrades just because rarekiller doesn't want to let the bot try before 90? Perhaps a counter, if I died twice, blacklist the rare until restart..
