Some suggestions, mostly quality of life, obvious things

I would hate see this. I see blacklisting people with the simple click of a mouse as anti-social. Reporting players with a click of mouse will cause a lot of unwarranted reports. If someone is worth blacklisting or a report, people will put the effort into it.

Have you seen the gold spam?
That aside, let's say I am anti-social (it's a personality disorder that people actually have, you know). What gives you the right to determine how I have to enjoy the game? If I want to block 200 people in the next 2 days, that's my perogative.
Now for some more tangible information: in the past 2 days I have had to blacklist 11 people. 3 of those were gold-sellers (whom I also manually reported), one a guy who kept stalking me, 4 were from obnoxious guild-spammers and 3 just deserved it. If that's a trend, click-to-blacklist is going to be very handy. Click-to-report, you make a good point, probably not a good idea- OP altered.

now that we know ARR will support addons I'm thinking most of these will be doable with addons

Ah, I was not aware of that- great to know we might get alleviation that way. Who knows, with the level of support SE have shown so far, they might even "fix" some of these before mod-support comes in.

And.... we have warcraft.... wonderful

That statement is an asinine masterpiece.
Whatever problem you have with That Other Game* does not invalidate the progress it has created/helped create. Most of these suggestions are present in almost every AAA-MMO.
Would you prefer a less player-friendly game, because TOG* has some of these conveniences?
Take your grievances and go.
