"I may play your game if you trim away a core appeal factor for the people who already play your game by splitting the active player base" is not that convincing a feature request to a gamedev.
Many live service games that are punishing for new players are still thriving like LoL and DOTA2. Much that punish-factor can be resolved by good matchmaking, putting new players mostly with each other.
I thought the core appeal was the loot that you get from the PvE.
But I'm just an interested outsider, waiting for the crashing player numbers for the devs to come to their senses.
Plus, not every game needs to appeal to every player, which I think is where games like that eventually have their downfall. WoW was talked about earlier in the thread, and Blizzard continuously trying to make it appeal to other types of players is what kept killing it.
It's OK for a game to exclude entire demographics of players. A PvP first game shouldn't try to force itself to appeal to PvE only players.
