I’d hardly call a three year dev cycle a rush, but other wise, yes the game is a joke on the graphics department.
To be fair, I have moaned in this thread about the MP, however I've just played the campaign this morning, felt very band of brothers, the gameplay was solid (although its all been done before, nothing really "new) and the graphics seemed a step up compared to MP.
Feels like 2 WW2 games stitched together.
As someone one Reddit pointed out, the inclusion of headquaters means you need to load the full HQ map, every time you exit the current game, hence the lobbies are slow to turnaround the maps, as for the reason it takes so long to get into a lobby, no idea - unacceptable in a MP focused title
