Seems to me that the problem is the competitive meta. Most likely, FF did not anticipate that spamming regular units would be so powerful compared to elite options. Spamming lists are expensive to buy but too good in the game, so a slight rebalancing would likely make the weird effects less. Hopefully this is in the pipeline, and much more likely than FF publishing cards.
If there is no mono-cutlture of 1-2 competative lists, then the problem becomes much less, since the cards can be borrowed for tournaments. This is how me and my friends solved the X-wing problem, if your have around 4 friends playing the game all with different list-preferences, then 1-2 core sets for a competative player should be more than enough.
If the cost is to high, diversify the local meta yourself. Be the change you want to see...etc. I also note, however, that I was able to find all the cards and models mentioned in the thread except Royal Guard regulars on Ebay doing a 5 min, search. So really, it all comes down to the need to play 8 regular RG instead of 4+2 elties (with 2 cores), for instance. Or putting in some Troopers and mixing it up a little.
As for me, if I a going into the skirmish game at all it will be as a strict scum/merc player, likely using Hired Guns and so on. I enjoy playing the underdog:)
