Want to level quickly? Avoid LFR! Players get almost no experience in LFR in MoP Remix.
On the PTR, players were simply spamming LFR Mogu'shan Vaults to level as it was quick and easy. Each boss dropped a «Bonus Experience» token that awarded a large amount of experience. On live servers, this bonus experience token is no longer dropping from LFR bosses and thus players are getting almost no experience from LFR. Bosses themselves are still dropping a bunch of loot, including Threads, Gems, Gear and Consumables, but no experience.
In completing 3 bosses in Mogu'shan Vaults LFR, I got about 300 experience from the first 3 bosses and trash and the following boss drops:
Boss #1:
Boss #2:
Boss #3:
The first time you complete an LFR wing in a week, you get Lesser Bronze Cache which awards 400 Bronze!
After this first bonus, you get an additional Cache of Infinite Treasure for each completion.
