If your intent (for games which conform 100% to Official BattleTech) is for SPAs to be spontaneous and innate, rather than the product of training and experience, the rules should not make a certain skill level prerequisite.
Your logic does not follow.
Well I don' think that you can simply replace a squad's leader with some guy with the Foot Cavalry and they get the benefit's
I'm not sure what that has to do with your 'reading between the lines remark' earlier.
Not quite what I said
You're not making sense. I was replying to something you did, in fact, say. It seems we're experiencing some miscommunication. Perhaps it's functional to simply have you explain what your position is, and we can then see if there's any agreement. Might get us out of the process of talking straight past each other.
Paul's viewpoint is that SPAs are genetic or something, and that there's no skill involved in learning them, so yes, it could be taken as unreasonable for you to require even the ability to pilot a 'Mech
A lot of things 'could be taken' as reasonable or unreasonable. That's irrelevant. What matters is understanding the original intent, for two reasons. First, if you seek to benefit from the common ground of published rules, it'd necessary to understand them. Second, if you are happy to deviate from published rules for your purposes (as you're welcome to), it's useful to fully grasp the original, as to also understand what you're deviating from.
An SPA is a remarkable capability or ability. The kind of exceptional performance that separates the merely competent from the truly outstanding individuals. That includes a requirement of Attributes, Skills sometimes even Traits merely to gain access to the potential. Crude example, you'll never know if you're capable of tremendous feats of car-control or sword-control if you've never wielded either device, and never progressed to a decent level of achievement. That level of achievement opens the door to a deeper understanding of the kind of capability you always kind of had.
SPAs should be viewed as inate talent manifesting itself, much in the way that Traits do. You either have them, or you don't. There's really no reliable way to train for them, and there's no rules to "spawn" them spontaneously like some sort of item drop in a MMORPG just by grinding a few million people through the training program. Heck, in most cases, they're not even something you can objectively measure.
You seem to have the notion that policy set by the military leadership can provoke a higher incidence of SPAs, and that's simply not compatible with their concept.
Do you follow my meaning?
