If you continue to dumb down the game, you will lose half your player base

That where you are wrong. This solo players leave after a month. Nothing solo players hate more that a unfinished story in an rpg.

6.0 finished the main story. That's stated by SE.

The changes now to make ARR and onwards more soloable is also stated by SE.

I expect we can expect another huge trimming of ARR and Post ARR quests to happen in coming patches to speed up the boring parts and help retention. Because ARR and post ARR is still mostly a boring pile of steaming cow poop.
