This is a fair point, but the issue is more that you shouldn't have to do this to download the update.
My problem was solved by changing the port in the XIV config.
Although as long as there's an alternative, it doesn't really matter. Now if SE didn't provide us with uTorrent files there would be a problem.
This is also the only reason why they haven't been forced to change anything. Honestly, this should have been the first thing they fixed. But while people can still find a workaround... why bother?
If people can't log in, then it doesn't matter how good or bad the game is... and there's plenty of people out there who aren't good with computers (example: I had to explain to someone a while ago that email addresses don't start with "www." and end with ".com". And when I try to explain uTorrent to people I know who aren't good with computers... well, it's like trying to explain quantum physics to a Frenchman. While speaking dolphin. It's just not possible.
People like that - technophobes - would either not think of Googling it, or they'd just give up entirely. And then there's impatient people who don't want to find a workaroundd, and will just not bother trying.
The problem is that, while a workaround exists... it's only useful for a percentage of the XIV community. And this is another contributor into the decline in subscriptions.
It's a real shame. I hope they fix it for you all, I really do. But forcing people to open ports or change their router settings, or use bittorrent... it's ridiculous. A company of SE's size should be able to fix this within a week of the problem occuring.
Which, incidentally, was in Beta. (And maybe Alpha too - but I can't comment, I wasn't in that)
