I usually play Hindenburg and I waited a lot for the Enhanced Repair Party. Finlay got it and it turned out that I had to remove Concealment module to put this one. It would make sense if this module would fit instead on the position 2 replacing the standard Repair Party, but it forces you to remove the concealment module which is (in my opinion) the most important module for a cruiser like Hindenburg.
On Hindenburg you will fear being hit for battleships the most and you will receive lots of AP hits since BBs like to take out cruisers first , so the actual repairing times that this unique module reduces are not so important compared to not being spoted so easily. I did play some games with the module mounted and the improved rudder shift did not help much because i could not see the other ships and i was always in Detected mode and got bullets coming from multiple directions. The game become more hard to play making Hindenburg a weaker ship for the role. Removed the module and installed the old concealment one.
I think this module is placed in the wrong slot.
