Feel free to add your own.
1) Why when someone pulls agro in a WoW 5 man, do they
jump and hop and run away from the tank?
2) Why doesn’t SW:ToR have an LFD? Isn't that the
standard now?
3) Why doesn’t SC2 have chat channels ala Diablo 1,
Diablo 2, Warcraft 3 and SC1? Not broke, don’t fix.
4) Why did Dragon Age change the style up?
5) Why when you say "This is my first time doing xxxxx,
so can you explain this fight?" and you die, do people
yell at you and call you a noob?
6) Why do you always forget to write down the names of
the people you enjoyed playing with, but the people you
hate you never forget?
7) Why is it when you see a piece of gear you want in a
5 man dungeon, run that dungeon 7 times, never get the
item, then run it once on an alt and get it first try?
Dungeon Siege III. Whyyyyyy??????
