"Immersive" would be the main thing above everything else for me (and the whole quasi-warrior-god as a female doesn't really do it for me), but I can't speak for you. I do know that speed isn't based on male/female though, it's based on the height of the race you are (and probably pretty small too).
As someone who had a mage as his main character, magicka is useless. You never have enough unless you enchant armor to eliminate the need for it completely, and at that point your base pool may as well be 0. Invest in stamina until you feel you have enough for however many moves you do in combat, then stop and put everything else into health. Health is the most important.
I know that speed depends on height, but this was referring more to Bretons. Male bretons are taller than female bretons.
And yeah, I have a hard time imagining the ultimate warrior as a female as well, but I didn't want to say so because the community seems to think I'm a misogynist, for some reason.
As for magicka, the main thing I plan to use it for is invisibility, and maybe a means of escape if everything goes wrong. I hear 200-250 magicka should be enough for this. Are you sure I should do the magicka reducing trick instead? I want to save those enchantment slots for other things.
Hold on, I'll list all my perks in the next post.
