@scarlettecrowe I have feelings on the timings of new content, but I have to address a couple of your points as well:
"what about players that just got the game?"
Well - they missed out on 4 years of content, so it's not like these few adventures will impact them. The world now is different to the world we were presented in 2018 at launch, or anniversary, or beyond
"a lot of us have to miss out because of work, school and other irl happenings"
Indeed, but would we not rather make sure we do those IRL things than play a game? That is not meant to be patronising and I get the frustration, but SoT will come to an end one day and I know I for one wont think "I wish I spent another hour grinding that adventure rather than getting my degree".
There is also the sheer fact that most players find there to be more than enough time to get the events done.
"missions being a minimum of four hours at a time"
What missions are you doing? I managed to visit all six fortresses, complete them, then get all but one Golden Sands resident found and do all the commendations in less than 3 hours of playing last night. I rarely do one thing in this game for more than a couple of hours anymore, unless on a stream with someone.
TL:DR
Yes, the timings can suck, especially for those who have other commitments, but we should just enjoy the game. Some stuff inevitably will be missed, but it shouldn't spoil our enjoyment of the game.
Apologies if any of this comes across as patronising, that's not my intention.
