Not necessarily, but ultimately this is a WB decision and the point where all this stuff gets rolled back could be months from now.
How long did it take for WB to react to the backlash that was the end game of Shadow of War?
I have been playing the game for some days now. To make the whole experience much better, they only need to change the difficulty of the single player towers.
TBH the grind itself is not as bad as it sounds, the problem is mainly that the towers you need to grind are extremely hard to complete, frustrating and plainly not fun most of the time.
The towers actually give you decent amounts of ingame currency, it's just that they are sometime impossible to complete.
That means, they don't even have to change anything about the monetization or currencies itself at least in the short term. Fixing only the difficulty of the towers would make the game immensely more rewarding very quickly.
At least for a hotfix-type of situation.
To be clear: the game would be a lot better without 7 currencies and a RNG krypt BUT it is not as intrusive as it may sound on pape if the way of grinding (towers) would not be so frustrating.
