No, less focus on things that don't matter to the overall gameplay and more refining of systems that do matter is what brings people back. ESO was awful now they've fine tuned a lot of the combat and the game feels much stronger, for instance I'm a level 10 dragon knight, my skills and stats give off such great feeling, where as in 14 when I pop a tank buff I don't feel that buff being activated. Aside from skills feeling much better, the MSQ is so quick in ESO that it's actually enjoyable, I can finish one MSQ walk to the town and be visited during my journey back that the next MSQ is open. Before the game took ages for the MSQ to open up each mission it was so dragged out it became an afterthought to exploring the world. It was very close to how 14 has its story flow, a lot of pointless quests that go A to B, pick up item X take to location Y, kill add at X location, run dungeon now or primal fight.
Honestly housing as is clashes a bit with the games lore at times it's a very hard to overlook, recall the end of 2.X when we thought the Sultana was killed, the Brass Blades were looking for us, but we owned a house and could go freely into and out of it, this was especially laughable if you owned a house in the Goblet. Granted ya you could go back into Ul Dah after this and it breaks the game, 14 needs less of this and craft a story that actually changes the world as we progress within the current story. For instance not even 3.0 does this, but we had Nidhogg preparing a massive assault, so why was the dragon presence so minimal in 3.0? Wouldn't a dragon seeking blood be sending out hordes to randomly attack us in the field? Nothing feels important in this game, which is hurting the integrity of the games foundation.
People don't want to keep playing a game that doesn't feel important nor as impactful as it should be. If SE wants to bring back people and keeping them hooked, the game needs to feel it's growing with the player and not staying stagnant, pushing forward and challenging the player is the only way this game can grow and foster more players. Adding more of X,Y and Z content that has issues that they haven't fixed yet isn't going to solve anything, it would make things so much more worse.
