Hmmm... Thanks, Tricky, galraen, and TheDeadShadow. You have all made some interesting comments, which I have taken onboard. With regard to Alteration, galraen, I use it mainly for the feather spells - Ease Burden, and such - but I guess I was thinking of my usual weak mage/stealth chars when I included it! I suppose it isn't so important for a Combat class Nord! And I take your point about Security: I'm pretty good at hearing when to hit the pick, so I don't really need it as a Major - again, in the habit of using it with previous char types.
Good points on that from you, too, Tricky.
Armourer I really like to have as a Major so that I can repair magical items as early as possible. Of course, again, my previous chars not having been Combat types, it was important to have it as a Major so as to give it a bit of a bump-start; less important with a Combat, since it comes with a +5 starter even in Minor. But... I'll have to think about that.
Block I have already in Major, but I really don't like heavy armour - though it is better protection, I agree. Maybe I'll give it a go.
Good point re: sneaking and Athletics. My chars almost always sneak outside cities and dungeons.
And yeah Marksman is a good skill for a low magica type.
But I don't think an Altmer would suit my idea of a combat class, TheDarkShadow, though I appreciate your point regarding me missing the magica, LOL! STR only 30 at start, and you start getting attcked with magic weapons and spells pretty early on, and Altmer have weaknesses to all elemental magic. I always combine them with a stealth so they can sneak their way past most trouble - and they have so much magic available they don't really nead normal weapons, so pointless, imo, to have 'em as combat class.
But thank you all. I shall go back to my build and start over.

You have been most helpful.
