Adding any type of heal not limited to focus or out of combat regen would compeltely break the attrition based system they've designed DA:I around. By having healing or OOC regen, it means that every encounter, to be worth fighting, has to be able to completely party wipe you and must be treated in isolation, as you'd just be restored to full health after the encounter. By instead preventing health recovery except for a preset amount of potions, the devs can design encounters that are instead designed to wear away at your health and potions over time and can balance multiple encounters together rather than having to keep them separate.
You're meant to have to go to a camp every now and then to stock up, although in general, I woudl recommend you push on to the next one rather than going back - and if you find you're doing it too regularly to be fun, turn the difficulty down.
Long cool down small heals would make things far far worse, as you'd be encouraged to sit around doing nothing after combat until you've had time to get your health back to full (and if you make it usable in combat only, you're instead encouraged to keep a weak enemy permanenetly CCed until you get you're health up which is even more stupid).
Attrition based system is the dumbest they ever did. It is basically based on BOREDOM and annoyance. The battles become "how many potions do I have left, now that the battle is done and I have 3 potions left, should I go back to camp or JUST PLAY THE GAME".
I loathe that decision they made. DA1 and 2 were way more fun in combat that way. I much prefer a timed based potion system instead. It still has tactics because since you can't pop one at will but it has a timer of perhaps a 1 min or so you have to be strategic, but have fun in combat and when the battle is done you auto-regen back or pop a potion which you can loot in the world.
DA2 was really fun in combat, actually enjoyed the waves of enemies because you felt powerful in all your actions, still had a challenge etc.
So far this game is about 2-4 enemies in EVERY encounter and they are all damage soakers and unless you overlevel they all make you feel like you hit like a little girl in the abilities. I want Assassinate and just One hit kill scrubs. Bosses should be a challenge, elites etc. But plebs should be easy to dispatch. That is what made combat fun and visceral in DA2.
The worst part about the new system is that you STILL have infinite potions, they just made it an annoyance by having you backtrack in the game to get them replenished. It kills the enjoyment of the game to think about heal potions all the time.
I want to think about the fun of being in combat, not if I should proceed and maybe end up in a no win situation because I cannot LOOT potions, But I have to run back to camp or fast travel and then run ALL THE WAY BACK and face respawned enemies etc. It is so cheap and idiotic I think it is 100% worse than anything else in any DA game ever.
Also they managed to make a perfectly good tac camera and system from DAO mediocre, and perfectly fun visceral combat and excitement of DA2 to something mediocre as well. Then they introduced an annoyance of limited potions and no healing.
IDIOTIC MOVE!!!
I never understand why they cannot fathom that what fans wanted was the BEST of both games, not mediocre with a new system of annoyance.
If they would have taken the great tac system for DAO it would make all the pause an play players love it. Do the same with real time combat from DA2 and all of real time combat would love it. LOVE across the board.
Also what is with the looting system. Why did they make that more annoying too.
