It seems to me as a newer player... A large part of the problem of no "difficulty" comes not from the fights themselves... Savage raiders, parsers, and elites die and wipe on savage raids all the time.. The thing that makes them easy is death has no penalty whatsoever...
I often watch high end raiders on twitch wipe a fight they already completely know 4+ times and then clear. The problem is that dying 4 times in a row does nothing to you except make the fight take 15 minutes longer because you'll just jump off the platform as soon as a clear looks unlikely.
4 man dungeons are entirely too easy though and there is no fear of death (which is incredibly rare anyways) through any point in the game at all...
