Hello to everyone who contributed to this thread - apologies for the long delay in response to this thread - we'll be going back and responding to some old threads to get them sorted out and answered. Thank you all for your opinions! We're really thankful to see all the different responses regarding the levelling issue brought up in this thread.
There were some really good points brought up about the issues with levelling up and we have been slowly working on improving the levelling experience for players over a period of time, and are continuing to do so. Since this thread was created, an experience update was released to better balance XP. XP gained from quests and daily activities were increased, and event quests, activities, and side quests give varying amounts of XP. We have a range of new content we're working on that will add new ways for levelling, and you can learn more about these through the previous GD blogs that were released, as well as some of the Droobletalks that have been released on the YouTube channel.
We can't wait for these future releases, and we hope the levelling experience has already become easier/more fluid and will continue to become so as future content is released!
