The dissolution of the Exrah in Infinity made many players unhappy. As I do not play the Combined Army, I was not one of them, but I certainly understand the deep displeasure at the dropping of an entire product line.
I guess the Exrah molds were troublesome for Corvus Belli to produce, and overall they did not sell well. Which, of course, are good reasons for cancelling a product―while Corvus Belli is friendly, they are also a business.
Dropping a product line hurts, though. I heard a tragedy of one poor new player who picked up the entire Exrah line a week before the cancellation was announced. And it seems with new units for the Combined Army like the Fraacta, Maakrep, and Rodok, the voids left by the exfilled Exrah are now filled. But―I had what might be a great idea for the Exrah while reading on the tease of the new mercenary character, Le Muet…
To preface, the entire Human Sphere get Mercenaries. While vanilla human factions can’t feature them for ITS and Paradiso, the option is there for play, and many sectorial factions featuring them widely. But we alien factions get no mercenary options―and there are probably more alien factions on the way!
So: since thousands of models still exist, some Exrah have survived in the story, and the Exrah were just militaristic capitalists―why not make Exrah mercenaries for the aliens?
Such could be a very simple patch to support players who still would like to use the Exrah in this new edition, without recreating an entire product line, and without unbalancing the new Combined Army. And, of course, it would be fun to occasionally merc some bug warriors for Tohaa.
