GW games, especially the sidegames are part of a treadmill. It is unfortunate, but realistic to not expect constant or consistent support for anything particular in side systems.

This is part of why I don’t build models to adhere to a competitive meta. Rules change so much that chasing the tournament scene is just exhausting.

I recommend, if possible, getting a group onto a more stable system such as all agreeing to an older or current version of Kill Team, or an alternative ruleset like Grimdark Firefight. I have found gaming is more fun when using rules not bound by constant updates.
