Hmmm... Positions? As in levels? Then I would argue that level 4, 6 and 8 could use an extra spell.

Blood/Fire and Blood/Astral is well represented and should not be boosted further.

Blood/Water and Blood/Earth are on par with few but solid summoning spells.

Blood/Nature got the craptastic Crossbreeding and Dark Vines spells. Blood/Death is suprisingly lacking any "Ultimate unholy power" spell considering the combination of dark magic. Blood/Air has only the somewhat suspect Storm Demons.

My suggestion is thus to add a weak Blood/Nature plant, fungus or transformation combat spell at level 4 (Feeblemind effect?).

An area effect Blood/Air combat spell at level 6 (random teleportation of a group of enemies?).

A powerful Blood/Death combat spell at level 8. I have no idea what would be appropriate though. Possibly a combination of several lowlevel effects into one mighty "rips your intestines out and strangles you with them" type of spell. Kills one target and scares the living daylights out of everyone around it perhaps? Or turns a group of enemies into allied low tier undead?
