I can agree that the transition to individual packs is for the better, despite the increase in the prices. The resin not so much, as from the set that I bought the pieces seem to have similar issues, if minor in comparison, to the Humvee. Specifically the bubbles that you mentioned, some minor mould slips, and on one of the crates a pretty substantial bubble that will need to be filled.
The small cooler came with that set that I ordered as well. A pity that all the launchers are Western, rather than some Soviet ones, but hopefully they'll release a dedicated Russian themed one in future for those states where there's a mix of launchers in service.
