I believe that the hostility is there due a lack of transparency on Relic's side about what is going on.
War Spoils is a perfect example, they could have explained why duplicates dropped and that the feature wasn't complete on Day 1 of WFA however they waited nearly a month to explain the situation.
In the meantime the community could only assume Relic's intent with the feature because they had very little information to understand how the system worked.
Just leaving the player base in the dark and hoping they'll buy your DLC / expansions on goodwill isn't going to work when that goodwill is exhausted due to the game running poorly since WFA and loads of new bugs being added to the game with every patch with no solid commitment from Relic that they will fix these issues that make the game so painful to play right now.
+1 The voice of calm!
