I believe a normal raid should not be that convoluted in terms of mechanics for random parties to complete. It might be fun for someone to wipe for 30th time in a normal raid just because you don't have that communication that's required to do certain mechanics, but I'm not spending 3 hours of my life in a normal raid. That's why we have savage, and until we get savage for pandemonium it's too early to bash on SE's creativity.
Normal raids should be understandable enough for casual players to complete.
