One of the bigger differences between how I see things, and how the bSP is designed, is that I don't see any unit I have on the table as 'more' or 'less' expendable. If it doesn't serve a purpose, I don't take it.
There are innumerable times when I'll move a hyperexpensive Assault 'mech first, and some cheap militia unit last, to shape the engagement the way I want or need it to go. It's not that the assault 'mech is more disposable, it's that I need to shape my opponent's reactions.
First off, honestly, unless you want to play the scenarios the BSAs were designed for (I don't know the details, only BT scenarios I've ever played were the four 3rd ed. intro scenarios and one game with a CBT group I wasn't entirely responsible for, not much of a scenario guy), I don't see why a dedicated combined arms player, or any combined arms appreciating player without X or Y time limitations would have any reason to touch said BSAs.
As far as expendability, it's not about their
worth, it's about their
mechanics. Evidently, sometimes, you'll want to move a "lesser" unit (say a Galleon) last and your biggest unit (say a Banshee 3S) first, depending on your needs...but they're all "proper CBT units" that use "proper CBT mechanics", one is cheaper, but they all use the same ruleset.
The BSAs are separate from the rest. Their mechanics make their survivability purely dependent on blind luck (or nearly so). The 40 damage dealing demolisher is just as brittle as a TW rifle foot infantry platoon, if not more so. BSAs don't fit in the CBT mechanics, period. They're from an entire different rule set that's tacked-on for ease of use in certain conditions. They are niche, but they aren't "niche units"...their nicheness is...set-up wise? Again, you can't look at them as you do porper CBT units.
I also play 'pressure games'-advancing units on a fixed course regardless of initiative outcome-but I don't always do it, and usually I'm doing it to create certain opportunities or to apply stress to the thinking (and force reactions) of my opponents.
This is stuff you can't do with things in the BSP/BSA fold-because no matter what you do with it, it's completely predictable on-the-fly.
Well inevitably they are predictable for proper CBT units but they aren't amongst themselves.
Again, they're not proper CBT units. In hockey terms, they can forecheck but they can't backcheck. They can force a reaction but cannot react, and its meant that way. They aren't meant to be as tactically flexible as proper CBT units. They have severe limitations to go along with their unique, "standoffish ruleset" that, while it blends well with the rest of CBT, gives a heterogenous game rather then a homogenous one. No matter how much you stir, the two liquids will never mix, one will always float on top.
The intent was stated by (was it Xotl? one of the 'spcial colored' posters at any rate) to be 'creating mook units for a scenario' which reads to me as "creating a pre-scripted outcome for your scenario".
which in turn, is almost useless to play-it's rigged for an outcome by adding a new set of rules.
I'm fundamentally against that as a concept. It's sort of "you might as well glue it in place as a diorama if you're going to slant things that hard".
Again, I can't talk about BT scenarios that much, but from a historical wargame perspective, you're never expected to win scenarios that were decisive victorys for the opfor, simply to do better then historically.
This being said, I guess, scenario wise, that BSAs mostly enable to put a "sufficient number" of convetionnals on the table to accompany the "main battleline" while not overly tilting the balance in that side's favor. In a sense, they enable to have conventionnals WHITHOUT "slanting things that hard" like proper CBT units (aka TW rule infantry and 'vees) would. I can't say for sure, bu I'd assume it's more of a balance thing.
And as for other kinds of game (say pick-up games as that's pretty much all I know), BSAs, while lacking crunch and tactical flexibility, still offer a level of tactical freedom, like I said, through pressure if not in reaction. If both sides have a more or less equal force of BSAs, then there can be no slanting.
