No, I believe they covered both points. Yes, experience gain itself was changed, specifically when it came to grouping with much higher level characters in a dungeon in order to soak up experience from that high level character easily killing everything with little to no risk to the leveling character.
That was trivializing the encounters, which our Devs tend to try to address when they can. How long the system worked a specific way before the change was implemented really isn’t relevant. Generally speaking, even when we know about an issue, sometimes the fix isn’t as easy as we’d like and may require a complete overhaul in a system. It is likely that when they were doing work on experience scaling they were finally able to address this matter as well.
Again, the bug was that the scaling wasn’t working correctly and wasn’t providing the experience gain that our devs wanted.
After months of feedback and data from folks using the current system, the experience gain in dungeons is being increased. Not to the previous levels, but to a level they feel is more appropriate.
Now, since the original poster found their solution, and this thread really shouldn’t have ventured into this subject, I think it is time to close it. Thanks, all.
