I find the difficulties to be completely unbalaced. Easy is not different from Insane. You will die in both cases, just faster on insane. Because:
Parry costs vigor
Controls stick, glitch, don't respond, respond with a huge delay and what have you
All signs exept for shild are plain useless
Most bombs are useless
And most of it is due to the shitty upgrade system. It is too slow, if we could upgrade faster then the game combat would be much better and more rewarding. Right now its just boring "Shield, hit, roll, run, bomb, hit and again" it is the same and works for every difficulty and ANY other plan fails even on easy.
Also would be amazing if they would fix the sign-bomb selection so we won't need to click to change the sign. That would make the game A LOT better, believe me!
