I've been using alchemy since I started Skyrim and while I love it, I know just about every combination. Since I've been relying on Restoration for healing, the simplicity of it is very relaxing given I don't have to open my inventory every time I want a potion.
Hmm. My other two characters rely primarily on restoration for healing, so I was trying something different here, but there is something to be said for simplicity, especially when playing a two-handed weapons wielder. One of the things I have enjoyed most about this build is the simplicity of combat. With my other two characters, combat was always a series of complex decisions, and I was always strategizing every move. For my mage, what combination of spells would best work here, given the number of foes, their location, whether they have detected me or not, terrain, friendlies in the area, etc.? For my sneaky Khajiit, it was can I take this guy down without that guy noticing? Can I sneak all the way up to the boss and take him out without anyone noticing? Should I sneak up on him from the left or the right? Where are the doorways? Maybe I should hide here int eh shadows for a while to learn everyone's routine so I don't get interupted when I am trying to slit that boss's throat.
Now that I am playing a two handed weapons wielder, the choices are much simpler. And I didn't think I would like that, which is why I haven't played one before, but actually I am finding that when my mind is relieved of the task of having to strategize combat, I enjoy the roleplaying more. I have been paying more attention to the conversations of NPC's, getting more involved in what they are doing and just generally getting more immersed in the game than when I play other types of characters that require more thinking and strategizing.
