Hi Keltos (and welcome)!
I suggest you to have a look at "Point Buy System" by Stephen Templeton
You can find it
HERE
.
Actually the army lists have a
core of units that
must be taken (30 points) and players play with
bonus points that allow players to pick
extra units (i.e. bonus points +30 / +40 / +50).
As you can see there is a sort of
unit value point like this:
4 LDR
2 LI
3 LB
3 LS
3 AUX
4 LC
4 MI
5 MC
4 W
5 HI
6 HC
4 WM
5 HCH
8 EL
Hope this might help you.
