To each his own play style, indeed; but I'm glad to see someone else who plays 1H+magic. Everyone that plays mage seems to play a pure mage.
I'm not a spellsword, and I refuse to be called such (I know you didn't but 1H+magic makes me think "spellsword"). Spellsword is a type of mage. I'm no mage. I am a magic-user, however, but I prefer to think of myself as an assassin since I focus on stealth more...actually its hard to focus on stealth seeing as how most of the stealth skills are useless things like pickpocket and lockpicking and the only stealth skills I really use are...well...sneak (obviously) and light armor.
I'm an assassin who happens to use magic. That's all, really. Perhaps Nightblade is a more appropriate title?
An Assassin is anyone who takes a stealth approach to killing (or as the orc from the Oblivion Dark Brotherhood proved, stealthing is optional so long as you're really really good at killing people and not getting killed yourself).
A Spellsword is a kind of combination mage/warrior who is proficient in both, well...spells and swords (or whatever weapon you choose).
Likewise a Battlemage is a warrior-mage who wears heavy armor and wields magic instead of traditional weapons.
A Rogue is a sneaky, trickster type who uses magic, bows and arrows, and anything else that might be useful dependent on the given situation.
This is all from the Skyrim guidebook.
Rogue is a close fit, but only because I refuse to be called a mage, and because I use whatever works best for the given situation (in addition to magic and one-handed I do use a bow on occasion).
I said Nightblade earlier because its referenced in-game as an adventurer who prefers stealth tactics but also uses magic...a sort of assassin-mage if you will.
Really that's what fits my character best since I do a lot of different things. Hell you might even mistake me for a necromancer with all the zombies I raise on any given day.
Assassin first, magic-user second. I am not a mage of any kind. I am a Nightblade(?)
