Situation is unfixable TBH if you truly want to take a look at all commanders.
Unless you reduce the pool of commanders from this

to this
http://stat.coh2.hu/okw.php
Any buff, tweak or nerf to a specific ability will impact another commander which is fine, up or meta.
BECAUSE WFA or UKF have like ±40 abilities/units for 8 commanders when in the case of EFA, they have 21 commanders and ±50 items.
You would need to remove like 5-8 commanders from EFA and redistribute the abilities, to actually make it work.
And these customers would request that said deleted commanders be refunded to them , rightfully so.
... And Relic may not be in a position to pay them, nor would they want a dangerous precedent.
To make things truly balanced, they ought to remove commanders completely, and homogenize
all 5 factions into mirror stats of each other. Who can say it's not balanced if it's all the same?
- Relic is no longer in the business of balancing COH2. They've moved on.
So it's that or complete homogenesation.
Look at, say, Worlds in Conflict. Now that's balanced
