Skipping doors can fit into one of many strategies. Although I am not sure it matter, I want to preface by saying that I play with an awesome group of guys. The majority of the guys are 300-450 prestige (not noobs).
When I play, I prefer to get completions and skip the doors unless it is a completely free chest. I prefer to skip the doors because I have almost all the gear I want. Completions on perilous and for the different classes are more valuable to me than stopping at doors. Also, speed running will net more experience and almost the same gold (because skipping 8 rooms saves quite a bit of time).
I also prefer to clear the board first and go back to chests. Hit streaks are higher netting more TEAM EXPERIENCE. I often play as a keeper or barrier/elementalist. For me, it isnt about kill streaks. But for the team experience it is about kill streaks.
That being said, I ALWAYS use my mic and tell the group I am playing with that I will stop at doors if that is the preference of ANYONE in the group. I have a preference but rarely force it on someone. On the rare instance I run routine, I hate stopping because I get almost no gold for stopping at a doors.. but again.. I still stop.
So I think lots of "pros" prefer skipping them. Lots of pros prefer stopping... and lots of noobs want to get kills so they rush through and dont respect your preference.
Just kindly ask them to stop. If they dont, go with the flow and do not stop either or find a group that respects your preference.
