No PvE wouldn't be happy, at least not for long. They might be happy for 2 weeks tops then after stomping/ cheesing their way through the year 1 bumped into year 2 content they will complain about having nothing new to do. About how the year 1 Raids should have been heavily modified so it isn't the exact same raid they just spent a year nuking. They will criticize everything about the bumped year 1 content from how it lacked creativity to how it didn't actually added anything new to the game but they'll keep playing for that loot. Then when they finally hit 320 they'll complain about not having anything else to do in the game.

Well some events for pve could fix this issue or even have events ever other week that brought crucible and pve together so we enjoy the whole game rather than parts of it but I get what your saying!

Problem 2 I do agree with as the loot system doesn't make any sense. Problem 4 is also another area that would be solid to build on. Problem 1 seems to be more tied to people following what youtube/ twitch people say over actually making a decision and you already know where I stand on problem 3. Bringing new content would definitely help address the aspects of this post that I agree with you on.

And there is the underlying problem new content there just isn't enough of it until they fix that good luck getting stuff like this

New content takes time and resources to produce.

I understand this but it seems instead of diversifying with new stuff they will focus on pvp

Destiny has always seemed to work in a pattern. Release an expansion that is heavily weighted towards PvE and in between expansions try to focus on balancing Cruicible, ATM we're in between expansions.
