After yesterday's patch, all good abilities and builds where nerfed to bring them down to the ones that felt terrible to play. Damage for many characters was reduced by 25-60%. The actual numerical stats on gear that you already owned were massively reduced. Armor, defenses and healing were all reduced. Experience and power leveling have all be nerfed and limited. A game that was already a bit of a slow slog though the mud with real challenges has become just an inevitable death in quicksand. To many aspects of the game were brought down at once which has resulted in a multiplicative reduction in the speed and enjoyment possible.
My level 98 Rogue's damage has been nerfed into the dirt. Armor was reduced, damage reduction possibilities lowered and my characters healing was cut by 80%. The game was good and challenging late game and now it is just frustrating, slow and tedious.
Now is probably a good time to start playing. They have brought the game enjoyment to the lowest level since release, so hopefully it can only improve from here. At least you won't know how fun it used to be...
