<snip>as I stated before, you are almost never standing directly in blood and when you are standing in the blood, you are more likely to be stunned or poisoned. <snip>
That is the point. When you do flesh sacrifice (which you do 100% of the time on your first turn if elf) it makes a puddle of blood under you. That means you always have a puddle of blood under you and you can use that puddle for reducing necro skills. This means in the first fights you have 2 x 2AP attacks plus 1 Mosquito Storm on your first go which is pretty strong. This is far better than an extra 5% on your attack due to extra strength - your attacks start with 6 or 7 and 5% of that is zero.
All day long enough AP to do another attack beats a small increase in the strength of the attack.
Would I do take elemental affinity just for that? Probably not, no (but I have, but only to about level 5).
I can't stretch this enough: Standing in blood is usually not a good idea
With Glass Cannon the last thing you want at all is liquid (I agree with you there). In that case I'd avoid anything airy and certainly wouldn't take blood rain.
I'm not sure how far you've got but later on they love stunning you. The necro-witch and the guys behind the pigs especially. Sometimes you find immunity gloves and then it is easy. Sometimes not and it is verging on the impossible.
I have just set myself a rather dull task of checking the amount of reduction One Man Army gives (with one player it is 2AP and 70%, I'm checking 2 players) and I'm finding it a bit boring trudging through it all again. Next week I'll be back and full of enthusiasm though as I will not have to bother doing every single little quest.
I do like your idea of a Necro Warrior and I will try it next. I'll take all your set-up (almost exactly) but I'm going to do dual wield swords not sword and shield. I want to hit harder as in my experience so far in this game it works better than being defensive.
A bit more attack means a bit more healing also
