Your call. But IMO you are missing out on some of the best parts of the game. Not sure I'd recommend starting on them now, but be in D1 or D2, the next raid that comes out I wholeheartedly encourage you to have a go at it while it's still fresh for everyone. If you don't like it fair enough. But not even trying it is like saying you completed Final Fantasy VII without getting the golden chocobo, Knights of the Round and beating Ultimate or indeed Emerald (or the slightly easier Ruby) Weapons. They are big optional challenges there to test you. Albeit in the days before Google and YouTube they were tougher, but the point still stands.
