Agreed guys, and well said. War is not 'fair', indeed most participants want to make it as 'unfair' as possible - in their favour!
The activation count is tied to 'activation size', and goes back in history past Napoleon to earlier times. This is why military formations have different operational and organisational sizes. Most wargame rules ignore these and E:A is no different. Furthermore rules rarely take into account the long term history of a military organisation; attrition, reinforcement, amalgamation, detatchments training, experience etc and although they may pay more attention to equipment, even this may alter dramatically between notionally equivalent formations. There should be a lot more "hurry up and wait" to be more accurate. Basically there are a whole lot of things that could be added or changed that contribute to the notion of 'activation' and impact.
Finally as the rules currently stand, even if both sides start out with equal numbers of activations, it is quite usual for one side or the other to have significantly more viable (unbroken) activations than the other in the 2nd and especially the 3rd turn.
Ultimately, changing the way that activations work strikes at the heart of the rules in so many ways. Changing this is likely to need / cause a significant re-write . . . and they do work reasonably well as they are.
