I totally agree, and the exorcism quests actually involves another quest giver from another town, and you can feel the weight of different character's approach to the world and feel their impacts. Some quests also involve referring to characters from the main quest, and have different dialogues depending on how far you progressed the main quests as well, which also wouldve involved some effort to include.

I have it on my deck as well and it runs really nicely, 60fps constant on low or some slight framedrops on medium but never below 40, the only downside is if I press the power button to pause, it never reconnects for me when I resume, so I gotta close the whole game and reopen it.

Also, I found that by binding L1 and L2 to R3 and R4 (back buttons), then Right Joystick to output Left Joystick, I can play the game with just my right hand, freeing up my left hand for other activities... The right joystick is only really used for scrolling long item text and zooming in and out in map, which you can do using the touch pad anyway.

Having more max mana doesn't do too much to be honest, like others said, try to get the 2 aspects that helps with mana, one is the Recharging Aspect another is the one that gives you mana when you pop cool down, they will help. Then just try to stack resource reduction and cool down reduction.
