How is it so fast levelling a Hunter?
mostly travelling, Rk is probably the quickest class to level in combat because of self heals, power boosts, damage and quite a bit of AOE and dots so when at full damage you can take multiple mob's, stick a DOT or two on them and move on.
But traveling from one end of the world to the other can take time, at first there were very few fast travel points but lots more have been added in game, even so hunters can simply pop between area's in a second and be leveling again. All the time saved add's up hugely by the end. But even after leveling, its the ease with which as a hunter you can gather crit parts and things to go craft armours for other characters that is so useful. Rather than logging a minstrel who was say IN moria and miles and miles away from anywhere useful, spending 20 mins traveling to somewhere to gather bits to craft for an alt, a hunter, presses a button and is in the right area in about 10 seconds, then ports to a crafting hall to craft and you're back.
Its just the most utilitarian class for those situations, likewise explorer is the best starter trade as you can sell ore/ingots/wood you gather on your travels, and turn hides into tailoring stuff easily. Again because of the speed boost in running out of combat, running between mining nodes and things is that bit faster, although more recently the Warden has a 25% speed boost, i've not played one high enough to know how good their mustering skill is compared to hunters ports, also not sure how good the Warden is as a class as not played with many high end content, and they don't really seem to fill any particularly roll perfectly like other classes do. Not to mention at least up to about 25 ish I think i got, they are boring as hell, 3 main attack skills in different pointless combo's, supposed to get better but early on its pretty much a borefest.
This is also because at certain levels and certain area's you can do be doing the lower level quests in 3 area's on opposite sides of the world and need to move back and forth quickly.
Also, for most classes but especially for the no in combat heals hunter, chosing human as the race, you end up with a racial heal later in the game thats worth 3k morale( a level 60 hunter will have maybe 4-4.5k morale on average) so opens up being able to take out hugely higher morale opponents who would normally kill you easily. Very little choice for hunters but human because of that. Shame my first hunter was a elf because I didn't know that, harder content, and killing elites, the difference the heal made was massive.
