EotM gives ~4-6 levels depending on the skill of the Commander, the amount of zergs you wipe, or wipe you and the amount of Arrowcarts the opponent throws around. It’s a solid way of leveling (especially if you’re on a Green server from what I’ve heard) due to the sheer experience gained, but also the amount of Karma, Badges and Championbags thrown around, each helping your toon once they hit level 80 (badges can be used for your first set of exotics for a relatively cheap price, Champion bags offer plenty of Scrolls of skillpoint for triats and utilities.)
Definitly get the Waypoints to important places. You might not get any gold for it, but you’ll get experience for it whilst it’s still valuable to you and a lot aswell. Later-on it’s only a nice bonus having the map open for you. Ofcourse it depends on what your toon is going to do, my WvW-only toons haven’t got more than 4 Waypoints on the non-WvW maps each, 1 in Queensdale and 3 in Divinity.
Do some map compleation, when that is booring you play some PvP, when you get tired of that you play some WvW, then you can join your guild when they wanna do a dungeon (Very good way to level), help a friend or guild mate and yourself with more map compleation(Loot/Keys/money and levels), craft a while now and then with your mats you have got from exploring the world, do worldbosses, have a birthday with your level 80 char and you will get a level up to level 20 scroll and repeat all this and I think you can find more to do.
Why did I say this? Well becouse there is so much more to this game than just level up to level 80 and getting full ascended/legendary gear. The leveling process in this game is in my opinion a tutorial to learn how to play your new class.
