Yep, in the last few months, I noticed a drop of activities from my Alliance fellows, the Leader had to replace a few, and those around are logging in less.
To be honest hard to blame them.
Massive drop.
Nope my alliance is still flourishing.
Drop in activity? Not really. People still do their thing.
Also, OP, why have you started like 20 threads in the last 2 days? Time to take a break, buddy.
