Something I've certainly noticed when it comes to skills is how bloated Geomancy and Hydrosophist are in terms of utility in comparison to every other skill. Both improve damage with earth/poison/water AND improve physical/magical armour recovery, and Hydro improves healing across the board.

Meanwhile, every other skill like Pyrokinetic or Aerothurge is just "5% extra damage a level" with not even an increase in something like your resistances. It feels really lame pumping those stats up.
