Honor

I've been super active and donating multiple times per day but my honor has not changed once since the merger. Am I the only one with this problem?

It may be because your alliance has not held a mine for An hour or more?

If your alliance fails at keeping mines somehow/hasn't been gaining prestige for some weird reason you don't gain honor. You can have 100000million donation points but with 0 alliance prestige you get no honor.
Also, honor gains the more prestige your alliance gains, not how much prestige your alliance is on.
