Also, buying servers isn't as easy as many people thing it is. I mean, yeah, buy one or two is a simple thing, but buy 24 more servers isn't as easy as to ask for food delivery. That if they actually can buy them, knowing how corporations work, they probably can't, meaning they have to navigate between their own departaments to ask for more server. Corporation may have other needs and priorities, money needs to be checked as it goes in and out... There's a lot of internal information we don't know. What I do know is, the big population boom was in late june, that is 4-5 months ago. For a problem like this, that isn't time at all. Specially if they were working on the final stages of Endwalkers, which are normally the more problematic and most intense.
I mean, it's not about defending someone or not, but the "they should have bought more servers" may not be that easy. I don't know if they should've done something before or not, but the excuse of "we didn't had time" seems actually pretty logic. And since then they've been supportive, communicative and transparent, which isn't the normal thing to do, for that at least they have my thanks. Normally teams close themselves in a shell, post a generic message of "please be patient" and don't tell you why, where and how the problem is and how they are trying to solve it. At least they are talking to us like profesionals should talk to customers. There's a problem, the problem is this, and we are trying to do this and that to solve it. That's far more important than any 7 days or some skin or anything of the sort.
