Special Abillity Costing

[Dio]

I am hoping to use each of the 9 or 10 different special ability costing formulas at least once among the original 24 special abilities. Do you have any suggestions for which abilities should have a special costing option?

Here are the costing options and default special abilities:

; Cost   = Cost factor of ability
;          1+ = Straight Cost; 25% increase per unit of cost
;           0 = None
;          -1 = Increases w/ ratio of weapon to armor: 0, 1, or 2.
;               Rounded DOWN. Never higher than 2.
;               Examples: For a W1,A2 unit, cost is 0
;                         For a W3,A2 unit, cost is 1 (3/2 rounded down)
;                         For a W6,A3 unit, cost is 2
;          -2 = Increases w/ weapon value
;          -3 = Increases w/ armor value
;          -4 = Increases w/ speed value
;          -5 = Increases w/ weapon+armor value
;          -6 = Increases w/ weapon+speed value
;          -7 = Increases w/ armor+speed value

There are only 7 special formulas.  As for what would make sense for each:

-1 is good for defensive abilities, such as ECM, Trance, and AAA (ECM and Trance already have it.)
-2 is good for abilities that are overpowered on high-weapon units; cloaking/deep pressure hull would be good candidates.
-3 is good for abilities that are overpowered on high-defense units; carrier deck is a good choice.
-4 is good for abilities that are overpowered on fast units; putting it on blink displacer could work well.
-5 is good for abilities that are meant for fast but weak units; I'd put it on drop pods.
-6 is good for abilities that are meant for slow defensive units; non-lethal methods might be a good choice.
-7 is good for abilities that are meant for slow offensive units; it's already on heavy artillery, and that's a good one to use.

That is very helpful and thank you for the input.
