Nobody is baby sitting the new players. People need to stop abusing the new players with tactics like leaving when people say they are new and demanding that htey answer some question they may not understand or have read.
It is not sabotaging runs to sacrifice some speed for reduced risk so you get the clear without a wipe. Sometimes that price has to be paid with the corpse of the silent speed runner trying to force speed run without communications.
Even experienced players seeing a new dungeon does not know how to properly do it much less speed run it. Just look back a bit an see all those that whined about Captain Madison in Sastasha HM. Most new/newer player do not know what is a speed run nor know how to handle a speed run. And they certainly wouldn't know how to handle the chaos when there is no useful or functional communication.
This is an arbitary criteria with no means to enforce it. If it was up to me I think people should learn to communicate in Sastasha from the start, but you can't force people to communicate, get a keyboard, or do anything specific to facilitate communication. The people you are trying to reach which this thread, or that post, probably isn't even going to get read by them. This kind of 1-way failed communication isn't going to solve any problems. So you need to start from the standpoint of what to do and what to expect in the context of failed communication. Do not treat silence as agreement to speed run.
That is false equivalence. The speed runner are the only ones trying to impose this regime on others. The new/newer players don't even know what they can or can not do to impose anything on anyone. The anti-speed run people can not stop the silent speed runner from running off and aggro-ing everything and wiping everyone and then turn around and cuss at everyone else.
Fundamentally communication takes time and it is the anti-thesis of what the speed runner wants. The pure speed runner would insist that any communication is time added to the run so it is no longer a speed run and that time spent communicating is sabotaging their speed run. But there is no way a new/newer or even experienced can be a mind reader as to where or what the pull is going to do, where stuff is going to be positioned and communication failure is going to be cause of wipes. The pure speed runner just want it all to magically happen for them on the DF and that is just wishful thinking. Demand that new players respond to some question is just smoke and mirrors to distract from that simple reality.
