I have recently got back to playing Oblivion and have even managed to work out how to install FCOM and all the mods that go with it.
I am now back to actually playing the game again and have realized that I don't really know "how" I am supposed to be using all the spells, potions and magic when in combat.
One of the odd (unfortunate) features of Oblivion is that the game seems to be designed to let you PAUSE the game/action/combat to let you take your time to riffle trough your inventory to perhaps use all kinds of things to restore health, mana and/or stamina etc.
I understand that you can "hotkey" up to 8 weapons, armor, spells, or items to keyboard numbers 1-8 so that you can "quickly" make it "active" to use when next press the "C" cast key.
What I don't understand is exactly the expectation on how it is players are supposed to deal with all this in combat. Constantly pausing the game every few seconds during a combat engagement to change the active item or weapon is a real pain and distraction to the gameflow and enjoying the game. Resuming the combat from the paused state is just as frustrating because the player now needs to "get back in to the flow of th game" and remember what was actually happening at the time they originally pressed pause.
I am familiar with how a game like Warcraft integrates un-pausable action/combat with a user-friendly customizable hotkey GUI that allows players to much more easily pick from a range of spells/attacks in "the heat of battle" without requiring them to pause the action. Oblivion is nothing like this. The GUI in Oblivion is so limited that players can't even see what is mapped to what hotkey without pausing the game and checking. You even have to press two different buttons to actually cast/use whatever has been selected (first to pick the spell/item, second to actually cast/use it).
So I would like to hear from other players how they play. Is Oblivion gameplay meant to be liberally sprinkled with frequent PAUSES to give the player to reorganize their inventory/spells/weaponry? Why don't they just use an interface like Warcraft where you can basically see all your spells, weapons and items organised on the screen at once to be used by pressing just one button (rather than 2).
I have found that most of the spells/potions etc are just not worth the effort to use mid-way through combat because constantly pausing the game to map/arm it to use it even once, then rearm something else is such a distraction. There is so much detail and diversity in the spells/potions/items to use/cast during combat but it is so hard and tedious and disruptive to actually select and use it.
