Q:
Fastest way to earn karma?
A:
you have several options for earning karma, but there isn’t one that is the most efficient, because it depends on many factors.
Edge of the Mists or WvW karma can either come rolling at 10k/hour or you could very well be sitting 30 min without capping a single point, it depends on many factors: presence of a commander who is willing to do karma trains, number of people zerging, your server’s position, etc… it is IMO the most profitable way to earn karma but it’s also the one with most fluctuation
Doing fractals 10 levels below your personal reward level can earn you up to 9k/karma per hour, but sometimes fractals take more than 1 hour. This is the most consistent way to earn karma
Doing world bosses and champ trains also reward karma, but at a much lower rate and is usually used to farm rares/exotics rather than karma
and no, karma boosters don’t work with karma consumables anymore.
