I, as a 5x speed server player, I think this update can be harmfull for those are low lvl because you update so fast that you can not do the expeditions/dungeons nearly unlocked. For example, I arrived to Africa, did some dungeon/expeditions and i am already lvl 25, unlocking a new dungeon but i even do not defeat the lvl 20 dungeon boss. When i reach this goal, the drop from the boss is almost irrelevant in terms of items to equip myself, since that before this update, I dropped some good items in a good pace to equip and defeat the dungeon monster at my lvl. To get equipments to clear the dungeon, even more players will be against each other in the auction, spending more money in equipments than in habilities points, causing weak players compared to the older ones.
I created my account after a forge event, where the players at low lvl farmed a lot of forge tools and sold it to high lvl players, so, my only strategy was a slow push, avoiding lvl up so fast to, MAYBE, reach other player status when i reach their lvl. Now, with this update, its over.
If you guys could show me where i am wrong or another point of views, please, let me now!
As a suggestion, the XP bonus could be applied at advanced dungeons or starting in a specific lvl
