I don't raid with LFG teams and most of my clan smokes but most smoke while playing. If it takes them that long then more realistically they are doing other things as well, smoking doesn't take 10 min. I smoke outside so I do have to take a few min to smoke if the raid is taking a long time. With a good group we can get it done in under an hour so i'm fine but with some people it takes much longer, most often on the challenge modes. I can smoke and get back before most are back from the washroom so I just wait until someone else has to break for that or something else. Either way, raids can take some time and LFG teams can be stressful so that may explain the need for a smoke but people need breaks for lots of reasons.
