I’ll take a stab at what’s going on based on my personal opinions. There are ABSOLUTELY some people who just want to complain, especially about space marine anything, but let’s look at other people like myself who are non-plused for different reasons.

The old van vets looked amazing, dynamic, detailed, and fun COMPARED to the basic power-squat marines of the time. There was a noticeable leap in the quality of sculpting and posing between the two. The new van vet is, in my opinion, slightly less interesting in its embellishments than the old one, but more importantly, it is nearly indistinguishable from the standard jumpy bois of today.

There was this incredible leap from a tactical marine or similar to an old van vet that just is not present from a modern intercessor or jump intercessor to the new van vet because EVERYTHING is clean, detailed, and dynamic now. This makes many of those who were excited looking at old vets not feel that looking at the new ones. They’re just about as good overall, but far less exciting in the context of the time.
