What I dislike and I have made it pretty clear is a lack of choice.
If you can prove to me that lack of healing is actually more tactical then I might consider your side. So far you have failed to do this. By adapting a mechanic used in a much more action oriented video game where damage mitigation is not simulated by abilities but is completely controlled by me you have only proven that they are further moving away from RPG elements, not that a lack of healing is tactical and certainly not that these ideas are new or progressive in any way shape or form.
easy.
barrier is a very timed spell unlike healing. its short and very powerful, so when you use it wisely it can be extreme powerful or total useless. additional the position of your chars is important because the small aoe.
block is mainly a tank ability unlike healing for everyone. so it makes tanking enemies and overall combat control way more important.
avoid damage, more important too because of the following.
the real deal is the limitation of healing. this kind of mechanic gives every little combat more weight, its not necessary a thing of live and dead, but when you do your fights shabby you will be punished for this through porting way more often back to camp. take your fights serious and this will be no problem. especially in an open world game where you encounter a lot of nonlethal combats this kind of mechanic helps a lot to make big parts of the content not trivial, only if you dont recognize this you will be forced to camps over and over again.
and for the action oriented combat, playing only in tactical mode because of high difficulty and there i am forced to micromange my party, position, timing of important spells, tanking, cc is so important i cant the ai let it play for me. unlike da:o where with proper tactics (and i mean just basics like tanking and healing orders) , a strong healer and enough potions i could mainly play the game on autopilot (except maybe 2 or 3 fights) on highest settings without consequences, so in higher difficulties da:o was way more the "action game" than inquisition
