You should work on event upscaling, since right now mobs just get massacred if there are quite a few players around. Sometimes it’s just hard to even hit a mob, because they go down in matter of seconds. Due to that events end in a minute or so. It’s not fun when someone kindly tells you that an event just started if it is pretty much over when you finally manage to arrive.
I’d like to suggest to add some veterans perhaps, or enlarge attacking groups, increase their hp or something.
Also level downscaling doesn’t work very well. When you go to low lvl zones there is literary no challenge at all, unless you encounter some champion level mobs. That’s why I think you should work on that too. And if you do that, don;t forget to improve loot to preserve the balance between difficulty and income. Make all zones viable for farmers, not only Orr, which I personally hate.
