Today was the first morning in ages that I've logged on. For quite a while now, the extent of my game time was logging in maybe once a week for a single TF at night, then right back off. My brother and I discussed this, as he hasn't logged on in over 5 months, and it appears that while we were both ecstatic for the return of CoH, we've both gotten from it about all we can.
I don't think this is something that can be fixed and much less fixed with curbing farming or adding more stuff.
The game is old. It feels old. It looks old. It has old design philosophies. It has an old playerbase. I suspect the vast majority of us are only around due to nostalgia. It'll be around this time until it's not again. I'm grateful that BZB was able to live once more but I've no illusions about the future.
