To get enough points for GNW registration you need 12 players to get all the 6 activity points for 3 days. From the looks you are 2 people short for this- I suggest making sure you have enough active players or creating some alt account to rise it up.

That's the thing, I made two alts and my leader made one alt. We both raised them up to level 16, joined the group and then did their dailies up to level 21 or above. The 3-day activity rate didn't increase at all, we were still stuck at 177 which we've been on for the past 2 days. We're actually 13 active people in our group and we have a total of 4 extra alt accounts. So that should be enough to register for GNW. Last week we registered and that was without these alts we made.

Hey

Unfortunately, It's been checked and group activity is working as intended.

I'll suggest providing a group meeting and establish if your members are actually doing their dailies and discuss possible outcomes.
