Theres also an issue with scale, I thought one of the points of updating fantasy armies for
AoS wasn't just a base change but they were scaling models up. Lizardmen standard troops like silly next to all the updated model armies which currently the new new armies look to have a more larger individual model look where each model means more than 10 standard looking guys back in fantasy as in each guy is its own hero sort of look which currently the old armies fail to fit. So already
GW is making some armies not really fit the new aesthetics and look outdated on re-release. Its not stratagy on the new lizardmen part its been lazy, if they don't care about lizardmen why should I.
Chaos got big guy models each brimming with individual details, each looking like their own hero on the battlefield and lizardmen instead of having unique individual saurus guys towering over human characters have:
pretty much the equivalent of a clan rat. Instead of giving lizardmen players something that fits the new game
Its laughable for a release for a whole new system. They took greater care and attention when re-releasing tau and that wasn't even for a new system with new aesthetics.
