The playerbase figured out that Haste is the strongest way to increase melee efficiency in the game.
DNC provides haste. I don't see this as a problem of perceptions and an unwillingness to consider alternatives.
SE has a way of providing 'support' jobs that really only wind up spamming 1 or 2 of their abilities 90% of the time. So DNC's niche is 'haste bitch.' Much like BRD is 'haste bitch' or 'ballad bitch.' Or BLMs become 'stun bitches' for much of their endgame. The list goes on.
