I have to agree
The rules from 2001 set are nice, but it makes everything very complicated. Espacally if somoene only uses the fantasy races against normal minifigs they have to act tactically to beat the fantasy races.
The best way is to treat them as normal minfig, but you could gife them some dice rolls, for example
On the beginning of your turn roll a dice on a 6 the skelleton is killed
Roll a d6 at the beginning of every turn on a UR of 10 a dead skelleton raises from the dead
(Yay you can make things fair by making the rolls the same chances. But your opponent have to agree on some house rules and he will if the chances are better for him. But the dice are on my side)
but you forget this things espacally in the heat of battle so just keep it simple stupid
