Also, your are suggesting basically to unify armor into one, but a lot more complicated.
Did you read my entire post? That's *not* what I suggest. I suggest a fluid system where attacking someone always helps a bit, but attacking the weaker armour is still beneficial. It's superior in every possible way to the current system.
I read your post, but your suggestion was way too complicated. So let my get it straight:
if you do a 100 damage with physical attack, the enemy have 100 PA and 200 MA, how much damage you will do to each armor?
Also, the ratio depends on the amount of PA and MA that the person have, correct? So, I do more magic damage to a person with higher MA? Or a mage with already low PA takes more damage of physical attacks? Or a fireball deals X% of it damage to MA and Y% to PA?
When I said that the armor does a good job, I mean that to prevent CC being too powerful. Also, nobody is forcing you to use 1 type of damage... Is optimal, sure, but because the enemies have different amount of MA and PA, one character can kill a enemy with low MA with magic while the other kill the enemy with low PA with physical attacks. Last, but not least, Lone Wolf is a very powerful talent that combined with other skills, you can do a solo run with it.
I beat the game with 2 Mages, 1 Tank and 1 Archer (on Classical)
even win against the Doctor true form with his 22k of PA, 11k of HP and 20k of MA
Of course, some battles would be easier if I invested only in one type (or better yet, invested on 2H than a tank), but wasn't that impossible. Even on my future Tactician run, I am playing to use a hybrid party (2 mages and 2 physical).
Anyway, sorry if didn't understand your post correctly. And maybe a split damage between PA and MA could be beneficial and like you said, can open to new builds and strategies
IMO doesn't make much sense to a magic spell to do damage to Physical Armor,
Why not? The armor is tied right to the items themselves. Should plate mail be completely invulnerable to fire or electricity? Should a sword pass completely through a magical shield with no effect?
I don't see any particular lore reason why the respective armors must be completely invulnerable to the opposing type. We can just say that the armor is not completely efficient against the opposing type.
Hm... You made a good point.
