While I have played in vanilla, I have to admit that I have done a grand total of one dungeon properly. Well if you count running into deadmines alone and dying horribly to the first mob and never wanting to do a dungeon again, then two.
However the impression I get while talking to my boyfriend the vanilla player, from reading forums etc, is that they took forever to complete. 3 hours in a dungeon? Really?
No thanks. I understand well that some people probably can spend 3 hours straight in a dungeon without afking - probably children during the day when parents are at work and older people who live alone and have some free time during the night or whatnot after work. I, however, have a family, a pet and a house to maintain, so 3 hours without afking is impossible to me Am going to pick the ''no, no time anyway'' option. And I think even if I magically had a lot of free time in real life, like, if I broke a leg or something and couldn't move, spending 3 hours straight doing one dungeon is not interesting or healthy. Eyes need short rest breaks, brain needs rest... Even most raiding guilds have afk breaks mid raid so that people can drink/go to the bathroom/rest their eyes/take care of any small matter irl.
