At least some of those are still possible.

I'll add some of my own, though some may have been changed:

Wiping to a whole tunnel in gnomeregan aggroing you from across the gap
Spamming seed of corruption into a group of the opposite faction in AV, even with just one warlock
Knocking someone off the bridge or snowfall in AV, preferably with the special snowballs you get during winter veil
Killing something that is way too high level for yourself by yourself (solo frost mage kiting elite 5+ lvls higher, or my latest example: killing the winterfall runners in winterspring with a team that was 10+ lvls lower than them)
5-manning (boxed or not) a 10 man raid boss at the appropriate level
Killing someone in the air by dismounting and blasting them while falling without dying from the landing (water is a good surface to do this over)
Killing a boss that is immune to your main source of damage (princess in maraudon with 5 lvl 49 shamans for example)
Clearing an appropriate level heroic without a tank or dedicated healer
Sneaking through a high level area on a low level character
Get killed by a fel-reaver because you totally didnt see it coming
Get killed by the rats in the deeprun tram (can be pretty hard to accomplish)
Kill the last boss in the BC raids (they are so epic)
Find the secret hut on the coast west of dun morogh
