People who consistently play the game keep the game alive and when most of them are playing havoc they should balance things around havoc. Which in turn will keep more players and they should make changes to havoc to give us more freedom of build diversity but thats a whole different conversation.
The average player who hops on for 2-3 missions and logs off isn’t going to care that thunderhammer got mega buffed for “heresey difficulty”, and if they want more of a challenge they should start out in lower havocs.
Like I said before I firmly believe havoc is the game, if you can prove me wrong ill take the L.
