Any Class Help Fastest Leveling Class 1-75?

So here's something I've been debating. What class levels the fastest 1-75 or so. Assuming morph set levelling since pretty much everyone does that.

When it comes down to it, it's hard to narrow it down.

Assassin/Warrior have the best early game imho, with aoe attacks lvl 1. Both have solid mobility moves, but warrior dps takes a big dive around 60-75 it feels like to me. Assassin feels like the better of those two.

Mage has the easiest time, with a built in heal, and has a solid mobility move, but getting to 21 'can' suck with no good aoe clear. But easy isnt necessarily fast.

Shaman is such a glass cannon and no notable aoe till 21. Their heal isn't reliable and their movement ability is just meh.

Archer's single target only dps till 21 hurts them a ton. But their free speed 2 makes up some of that long term. Again they feel like they suffer dps wise in the 60-75 range. Their movement ability is better than shaman, but a bit lesser than assassin imho.

Just looking for opinions.

 

shaman lol

 

Shaman has a low lvl relic named stress which gives 39% xp bonus + shaman has good aoe dmg

 

I think shaman has the most notable early game AOE, with a 10 block totem radius, the damage ticks land pretty consistent on enemies
