Have you ever tried magic? I've played through several iterations of this game throughout it's versions, not once have I struggled on very easy - and I'm talking 1-2 shot any of the battles with anything. Only early Noo and Vhidna before you can get anything going at all is "difficult".I'm sorry but... how??? I honestly find the gameplay for the fights with the main bosses extremely grindy and annoying. (much worse than tower of trample for example) As in, I have almost 12 hours of playtime, (lots of that time I just spent trying to get events at college or in the city with the various girls, but still) I'm energy level 17, I always use mental preparation before battles, (and keep reactivating focus! when it runs out) and Miki is still virtually undefeatable! And that is on "very easy", not on easy mind you! I also make sure to hit all the QTEs, but it's pointless, cause she always eventually one-shots me with a "compell"/"face trample" combo, which is enough to deplete my whole lifebar before I even get the chance to drink a potion!
I like this gam.....
It's made even easier since some versions back when you unlocked access to Ayleens Katalist "element" to absorb or whatever it is, that essentially doubles your magic dmg. Literally hitting for 3k-8k in a single spell depending on gear regardless if you're level 4 or 24.
I am not saying you are "playing it wrong" but more so that the games balance is probably wildly unbalanced and just changing your tactic should be enough to not struggle, Especially on Very easy where you "should" easily be able to kill them so fast you don't even need to pay attention to the "tactics".
