No sorry I dont understand your argumentation. Why is that a bias at all?
Every sphere has their own kind of strenghts and weaknesses, why shouldn't there be sphere specific souls in game which support those spheres mindset?
Do you say all spheres should have such a soul?
Why didn't you complained when Cait sith was released (one of the best sp generator and card retreaval souls if not the best in game)? SO you mean all spheres should have this kind of soul?
Why didn't you complained when Chaos form zalzaguls soul was released for lawtia a nearly conditionless merciless death for 3 sp? So you mean this soul is fitting to other spheres midset too and they should get such souls ?
Why on earth is it repeatedly a falkow card you want to have changed? where you admit yourself you dont play falkow at all? But ok, I dont mind if we talking about this card. And i can understand you are sensible to falkow if you play refess.
The first thing I ask myself when comparing to the other 2 is: for a sphere specific soul why on earth is this one so damn weak compared to the other two. Other then that i dont see any bias, or if there is any please explain me.
Pera I value that you care about the game and about balance, but i think you should rethink some of the concepts you blindly assume about balance. Simply because they are not realistic.
