Experience and rate of progression has been a sore topic with the community ever since RIFT launched the server two weeks ago. While some felt fine with the deliberately slower pace of progression, others found themselves underleveled and without any quests to fill the gap. So three times the quest XP should help with this going forward.
Players will find that dungeons are a little less lucrative with this hotfix, as the bosses are tougher and the cosmetic and mount drop rate lower. Some bosses have had their damage output nerfed, however.
The hotfix also targeted “back-end adjustments” to help with the occasional appearance of the fearsome lag monster.
