Why do casual players have to finish questlines in dungeons?

Why do I have to finish a questline by going into a dungeon? I am not a dungeon player as they are all wham bam thank you Sam! Race to the finish, if dead you stay dead no rez. by healer, if you have something to get for a quest your left behind and then kicked. No respect for beginner players. Is there no other way to complete these quests w/out going into a dungeon! The basic player has been left behind by WOW it seems. Not everyone wants to go into dungeons but we want to complete our quests. I’ve been playing since 2007 and no change to this scenario in my opinion! Make the final quest challenging but not in a dungeon! Especially professions quests! IMHO! TY for letting me rant!
