I can't say I am thrilled about the change, especially since the new material resembles soft plastic (the sword of the Sergeant bends easily), but at least it was not the bubbly horror of Finecast.
Edit: After a closer inspection, I can attest that there are bubbles, but not as many as in the other finecast products. Still though, unacceptable for that price tag.
via Forgeworld when addressing this issue before
"(...)To address your points, however, we'd like to point out that Forge World do not sell Finecast products; Finecast is a Citadel brand, not a specific type of resin, and so we are not operating some sort of scam as you imply in your e-mail, nor are we misrepresenting our products. As we are perhaps the largest single manufacturer of resin models in the world, it should be unsurprising that the Citadel decision to begin using similar materials a certain amount of consultancy with ourselves.
"Forge World use a huge range of different types of resin and just as wide a range of casting methods depending on the kit in question. You'll note that the resin used for a Titan is very different for that used to produce solid resin scenery, or a smaller resin infantry model, or indeed the new range of hollow resin scenery that we're starting to release. What you describe as 'Finecast resin' is simply a different mix, one that we've used for some time for smaller and more detailed models where appropriate.
"The centrifugal casting process used to produce the Citadel Finecast range is again something that Forge World began looking at some time ago; you rightly point out that the traditional drop-casting method is extremely time- and labour-intensive, the spin-casting method is just as involved but the quality checking is rather more critical. This has obviously not been performed as stringently as it should have been, but as the Citadel and Forge World production teams are separate we're obviously unable to comment upon, or influence, the policies in place regarding Finecast."
