Go put this shit on your BLIZZARD ARE DUMB blog or something.
One thing which could do with adding which would make sense on RP servers as well is notes on the (mini)map, and possibly the ability to share such notes with other players.
That way you could even point people to coordinates, but it'd be indirectly (By adding a note to their map), as opposed to directly (By telling them the coordinates).
That seems more within the realm of scope of Blizzard (considering they've talked about putting an itemrack/threat meter built in), but this is a company notorious for not doing the "smart" thing the first time. Or the second time. Sometimes they get it right on the third time, and usually by the 4th time things are smoothed out to the point of mediocrity. They're also notorious for changing their mind when it actually comes time to impliment the things they said they would.
It's awe inspiring that nobody's been able to come up with a decent competitor to WoW in the PvE raiding market that actually has some PVP for players to engage in.
