Health regeneration potions? I'd rather just have...health potions. Oblivion's potion system was fine. And Skyrim's will be fine. Don't fix something that isn't broken.
Oblivion has regeneration potions, too.
Yeah, I saw the swallow potion in use, it was completly useless and did not help at all, the person I watched playing had to rely on not getting hit at all or as little as possible (yeah, again thats more realistic, but TES is a fantasy game it does not have to be realistic)
Witcher is also fantasy, what the hell is your point? Maybe you should also base your judgment off of games off of games you've actually played, not watched. I'm playing Witcher right now, Swallow is a life-saver in tough fights, and many potions are for that matter, but they have to used wisely. And potions should be in TES as well. Morrowind and Oblivion have comparitively shallow and boring combat systems that largely consist of just depleting the enemies' health faster than they can deplete yours, they don't really encourage smart fighting, and the way potions are handled is partially to blame. As opposed to other games, like Witcher and Demon's Souls, where you'll have to be much more careful of when to quaff something down, or else you'll just get your face beat in. Moreover, they make the quantity of potions you carry somewhat moot. It won't matter if you have ten healing potions on hand, or a hundred, you can still die fast if you don't fight intelligently.
and again, you over dramatize the affectiveness of potions, they were by no means a get out of jail free card. they were uncommon unless you made your own which to a long time of effort to make a moderate amount of them so there was never a quick and easy way of acquiring a bunch of potions. so if you spam them you pretty much don't have alot of potions for a while. at best potions are great at keeping you barily alive, the only occasion that you need to spam potions (which the limit was 5) was when fighting enemies that are going to kill you any ways if you don't have them. its a none issue for most people, I get that its an issue for you, but it doesn't merit changing the vanilla system and there is no need to force a more redundant system on every one.
Uncommon? Potions are given away like candy, are incredibly cheap to buy (and money is overabundant), and training in Alchemy only makes them more plentiful (ingredients literally grow on trees). By the end of the game, you'll be carrying a whole truckload of them, more than you'll ever need. There was a limit to how many you could drink in any given time, yes, but it was fairly contrived, and really not enough. I could count the number of times it came into play for me on one hand, and the number of times it actually proved to be an obstacle using zero fingers.
I see what you're saying, it's just that I don't want, or need, animations for everything. If they're going to add drinking animations for potions why stop there? Why not add a "loot body" animation for every single time we loot someone for all those people who scream immersion?
Nice strawman. This isn't about 'IMURSION,' it's about gameplay and balance, it's about knowing when is a good and proper time to drink that potion, whether it be to restore health, magicka, stamina, or get some neat effect like Shield or Reflect. And wanna' know the best thing about such a system? It's completely two-way! Not only can you see when the enemy is using a potion of their own, but they're just as vulnerable as you would be should they take a swig. Seems to be a good time to strike them as hard as you can, no?
