You're supposed to want your class to be able to differentiate itself from others, to have it's own, separate gameplay style. Otherwise, let's just scrap all classes and go the cookie cutter korean type game way of having "the warrior, the mage, the archer" and be done with it.
Hunter's mark should remain not only because it brings flavor to a class but because it's also useful in PvP for keeping track of rogues and druids, who in turn, ask for help from classes which can dispel the debuff. This starts a feedback effect in PvP, be it arenas or battlegrounds or even world pvp, in which players are able to interact with each other beyond getting healed or getting killed. It's small stuff like this which gives more depth to the game without necessitating big developer investment in game systems. The mage's "detect magic" was also one of these types of buff/debuff areas of the game which have been removed for no good reason and hurt the game in the long term.
Wanting quick, snappy, reaction based combat with little investment outside of pressing keyboard buttons has it's place, to be sure. The warrior class has that in droves, it's one of the reasons i've mained one for the last few years. But you shouldn't deride those who want to see more depth to combat and more options to the way they can affect it, even before engaging in it. Hunter's mark is one of those abilities, which, when used properly, can turn the tide of battle when fighting any stealth or invisibility using class.
If i were to have any input in it's implementation, i'd definitely choose the off GCD version, even if it will be macroed by heavy PvE enthusiasts, who seem to be the majority in this thread. Even if it's to be implemented as part of GCD, i'd still want it ingame because if there's no hunter's mark, you're only a ranged rogue or a mana-less mage at the end of the day.
