Who needs nine different shields/magic armors and six different ways to heal?
It helps to have some variance to healing role, and not all heals are appropriate to all situations. You certainly don't want to sit there pressing "Heal", cooldown, "Heal"... Let's say you're up against Mr. Poison. Mr. Poison poisons constantly -- it's almost impossible to just remove the condition, because he just keeps poisoning. So maybe you want a small Heal over Time, just to counteract the slight DoT. A character is about to wade into danger, taking a high-damage shot perhaps, and it's uncertain at what point he'll take the hit and he'll need
immediate healing afterwards -- something like Lifeward will be handy.
I'm not saying
Origins was the best at this, but I think
Inquisition is a step in the wrong direction (though I don't have a problem with removing healing persay, just to be clear). It's just... activate barrier. Your all-purpose damage mitigation. Watch out for your cooldown.
While I understand wanting to try different combos, there's no real point in having six shields that all perform basically the same way, nor is there any real reason to have five offensive spells that pretty much do the same thing. What's the difference between a frost spell that gives 100 damage and freezes the enemy for five seconds and an electricity spell that does 100 damage and paralyzes the enemy for five seconds? Nothing, unless the enemy has resistance {and that doesn't happen frequently enough to warrant four spells of the same thing).
And that's all true. But I think a better solution would be to try and vary the shield's purposes: make them unique, beyond "electric version". Surely there must be some way to change them around? This is a game that proudly boasts a tactical camera, it shouldn't be needlessly convoluted, but it shouldn't be simplified too far. Though I admit, with shields in particular I find it hard to imagine much variance.
Of course, Casual difficulty should still be available, so you don't
have to stress over it, if you don't want to. Not that Casual mode should just be "everything falls over and dies in a second" (unless they introduce "Narrative" difficulty, ala
ME3).
