if they release new structures: they will match the latest unit skins. tyrador structures(terran), cerberus structures(zerg) and ihan-ri structures(protoss). on the other hand: other war chests could add other structures.
All Protoss skins so far look interesting, Terran is kind of the ‘golden age look for Terran’ how Protoss golden age were. Zerg have the most boring skins of all from all warchests this is the worst, but their mecha zergs were the best so now it’s turn for worse
War Chest skins are technically Early Access for supporting the pro scene via War Chest purchase, hence why buying it and playing/watching SC2 unlocks the skins at a massively discounted price.
Early Access tends to have a few mistakes and/or bugs here and there and they’ll be fixed before they’re officially sold in the shop a few months after the event’s over.
They fixed it. I noticed it when I watched a streamer play with it then re-equipped the skin myself to see it true.
