They’re there in basically every customisation or “I guess the Alliance needs something” thread. Never popular enough to upset the bigguns, but they’re there. If we want some stuff, here’s one implying they’re a regular enough feature that they’re not wanted as a whole race but customisation
But the thing is, they’ve never been popular enough to get their own thread. They’re a mainstay of the threads but not popular enough not overthrow any of the regulars
(now, if only they were a bit easier to search and didn’t have a whole faction and a popular server with the same name…)
