I got a new computer when Diablo 3 came out, and I was just thinking about loading up again. As a hardcore fallout fan, I WANT to like this game, and there are many, many things I enjoy about it. One of the major dissuading factors is that PvP does not meet my player expectations. If I want to take this game to culmination and attempt to compete directly with other players I need to make many, many alts which don't correlate to my concept of what I would like my experience would be. If I run into another player in a town that is hostile I would like a life and death contest between those two characters, the victor gets to live, the loser is relegated to the wastes. As I see it now I must have between 3 and 7 blue suit specialists that reside in video game land rather than postapocolypto California. If I roll in to a town, and I don't have 2 or 3 alts outside waiting, then it is not even worth showing up. Even when the AC problem is solved and other exploits are sussed out, the lack of log in timer is a huge problem for me. I don't like waiting, but preserving the immersion of the environment is more important to me. I know this is a difficult problem to regulate, and I do not blame the development team for this, as I know they are working from a passion and doing their best. Fact of the matter, this is the major thing that has been keeping me away and if I didn't mention it in this tread I would not feel that I was living up to my responsibility to the community.
I suspect some folks will be tempted to respond with "log in timer is no good, folks just find a way around it anyway", to which I will respond in advance: A problem that is hard to fix is still a problem. It should be looked at in the eye and confronted, not ignored and labled "by design".
TL;DR: The lack of a log in timer kills immersion for me.
As always, in all honesty, thanks for your hard work devs. I know reading stuff like this on the forums can be hard to choke, even after all this time, but we only bring up stuff like this out of a genuine interest in what you have made for all of us.
