People are having a collective meltdown because their not understanding what has happened, haha. It really depends on where you were grinding pre patch. Quint Hill got hit pretty hard, and whether you were over the cap or under it will feel worse now due to the mob buffs: Def +30% / HP +170%. While Hexe only got a +16% Def buff.
Basically, if you're over the cap for a spot you'll still do as well as you ever did UNLESS the mobs at that spot got buffed, your performance in that case will depend on the strength of the buff. Quint Hill feels bad, while Hexe is great.
