I believe from the JP Patch reading, Yoshi P stated that they were going to discuss the reasoning behind the changes to Samurai, and I believe future changes and direction with job design as well, as he mentioned that crit synergy in general is a problem. I don't want to get to irate before hearing this out, how ever I believe changes like this, as well as changes that were made in ShB like to monk, feel like they should be held off on until the next expansion or until the end of the current expansion.
Housing is never going to work, not with out adding instanced housing. I am still of a firm belief the biggest mistake with housing was allowing singular players to purchase them. I understand there are loop holes around that, but those loop holes are also inconveniences to many as well. You will never see a fair housing system unless it is given to every one. I believe the most ideal change, would be to make every players inn function like an upgradable inside version of a house like an apartment or FC room but upgradable to larger sizes, while the Island Sanctuary functions as the outside portion of housing. It's a separated experience but gives everyone the same capabilities as owning a house.
The problem with the MMO to RPG is really in it's direction. The game is pushing more accessibility to things such as savage, which is content that many players choose not to do for what ever reason. Making this content more accessible isn't doing anything but making job design and raid design suffer. There is nothing wrong with having a high skill ceiling, most of the most popular games have it. That skill ceiling also does not have to affect everyone in all content either.
I know they are currently focusing on correcting the housing lottery system, but I am eager to hear what they have to say about some of these concerns specifically with class design.
