Can we count those who have been away or don't run certain content very often among those who NEED to speak up? I've seen some players rant in various venues that if you have jobs at 70 you must have everything down perfect and know it all. But I've also seen many players in DF who come and go for various reasons and are rusty or who may have only been in an instance once or twice (or not for months). And they don't all have a returner's crown (or it wore off). I think these players may be embarrassed to speak up that they are not confident in doing big pulls or that they don't have particular boss fights down pat. Yet they have some baseline skill and knowledge that could be encouraged or developed.
And yes, in my humble opinion if you are using DF solo or with one friend it shouldn't be a shock that you may need to take an extra 10-15 minutes to complete even if everyone is constantly casting and has a firm understanding of at least their 5-7 primary job skills. Why try to force speed runs rather than just ask if that's cool at the beginning? The former often leads to wipes, which leads to bickering, pouting, people throwing a tantrum to be kicked, people taking the drop penalty and sitting in queue again, waiting for new players to join in-progress, and votes to abandon, which make the run even longer, less pleasant, and turns new and experienced players off from the game. It isn't just your time or my time that is at stake. I totally understand being frustrated when things could be better/smoother, but if you have to have that fast clear why not run a pre-made or at least ask the DF group first if that's cool? I also get leaving when it's just too stupid, but again, that's what this thread is about? Where is that line?
It's funny, but, for all the horror stories floating around there's a large segment of players who want to learn, practice, get tokens, meet people, etc, in DF but they are caught between those with the "this better be fast and perfect" mentality and the "how dare you point out I am only using the first skill my character learned" mentality.
