Just for fun, and because I'm in pain waiting for this, I'm making a list of "seriously all of these things can get you XP" in Guild Wars 2. Please let me know if I left anything out or any points need clarification. Shall be making a Gafguild thread for further discussion on this most glorious of topics, if you're registered over there.
Seriously All of These Things Can Get You XP in Guild Wars 2
Renown Hearts (closest thing GW2 has to traditional questing)
Dynamic/Meta Events- sometimes following an event chain will net you enough for well over an entire level's worth of XP if you follow itthrough.
Dungeons- replayable, can be done in either story or explorable mode, always with lots of XP
Personal Storyline- each storyline quest gets you a big ol' chunk of XP
Skill Challenges
Vistas
Daily Achievements- a set of
things you can do once every day for a bunch of extra XP. I didn't know about this in time for any of the betas/stress tests, and still got enough XP from other stuff to get to ~level 20 without repeating a single event/heart, so this blew my mind.
Hidden Achievements- things like completing jumping puzzles, for instance, often get you an achievement, and those achievements get you XP.
Exploration- yes. literally JUST the exploration itself gets you XP. Go to an area you've never been before and poke around = XP. This includes cities, many of which are totally massive and have plenty of incentive to explore
besides the XP. But you get it anyway.
Reviving players- taking some notes from TF2 on this one... reviving a downed player gets you more XP than killing ~10 of your average mob. Mmmm, incentivizing teamwork.
Gathering
Crafting/Cooking
oh and
Killing things- yeah, it gets you XP. But just because they couldn't even let this
basic concept go without doing something awesome, allow me to explain the concept of
Bonus XP: the longer a given mob has been alive in the gameworld, the more XP it is worth above baseline (you'll see a popup of Bonus XP +Whatever when you kill it). So if you go way off the beaten path to a totally unpopulated wilderness area, chances are the stuff you kill will be worth substantially more XP. Plus you can guess the relative age of creatures by how much bonus XP they're worth.
