Give me a legitimate reason to NOT have a LFD tool.

No, you asserted that WoTLK came out of the box pre nerfed so any additional nerfs couldn't possibly be the result of an auto grouping tool. Then you cited halls of reflection as evidence that LFD could come with harder content as well. Everyone who played at that time knows that halls of reflection was the bane of LFD. It was the one instance that sort of demanded respect thus was miserable for most people to do via LFD.

If HoR popped in my LFD queue, I would usually have to wait awhile inside the dungeon for people to show up, realize where they were, and leave the group because getting the 15 minute deserter debuff was well worth not having to run HoR via LFD for them. Thats the success story you get when trying combining challenge even to a moderate extent with an auto grouping tool like that.

This is in an ideal situation. Server A gets a longer queue time and server C gets a shorter one. I repeat again. The average of three numbers CANNOT be LESS than the smallest number. So if the shortest wait time on any server is ~15mins

available an average of 4 times in one hr.

have 2 sets available to them within that hour.

Now ALL servers have 3 sets of tanks and healers available to them in the hr

The average of three numbers CANNOT be LESS than the smallest number.

The average wait time in queue A is 15 minutes; 4 groups form every hour
The average wait time in queue B is 20 minutes; 3 groups form every hour
The average wait time in queue C is 30 minutes; 2 groups form every hour
The average wait time in queue D is 6:40 minutes; 9 groups form every hour

where is the math error?

So after spending all this time complaining about the prospect of Bioware dumbing down the game, you tell me that you actively avoided running the more difficult content? Effing Brilliant. I guess it's my fault for taking you seriously for as long as I did though.

That's your problem: there's no such thing as a "wait time per server", because there isn't a server queue. There's only a wait time per group, or a wait time per person.

I wouldn't be able to tell you how I'd usually have to wait for several people to leave in the begining of a HoR run if I were avoiding it now would I? Again, you're just amazing.

They ran them to get the rewards at the end, and felt compelled to run them over and over and quickly became both jaded and with zero patience or tolerance for newer or lesser geared or skilled players. In short, it started making pretty much everyone miserable.

Dont forget with Cross server LFG, if you get stuck with a loser you will never see that person again most likely. If a loser is on same server you stuck with them.
