Selichos is so important. Many places DO daven too fast. Too fast means not giving time to contemplate and think even a little about what one is saying, only to rush thru saying words we do not understand and concepts we are not grasping. Selicha is begged, not said, so we do not go to say selichos rather to ‘beit’ or ask selicha. A minyan that begins ten mins earlier makes all the difference.
Incidentally I was also told like Aaron Chaim said that the most important part are the few pesukim between before beginning the new selicha, while of course the yud gimmel middos are never rejected by hashem if said properly and we live by those middos ourselves.
