I have been testing out this group limit change and wanted to give it some time before jumping to any rash decisions. After a month now, we have a good evaluation period. The thought behind group size I understand, try to make game harder and avoid chance of bots for any filler spots. The issue is that its not exactly what is happening.
I've led a fair amount in this game and still lead groups this wipe. I find with 8 limit group I am having to really pick and choose the folks we need in groups since things are harder, along with half the group has crap natural stats :) The folks who get left out typically are mages and people who just are not as skilled in the game or maybe not legend. I try to include sub 30's/non-legends but when push comes to shove, you take legends for harder zones. The theory of 2ndary groups rarely works out. I would love to take along more people who just want to zone and don't know much, but group limit change has made that difficult. More people we can bring along and zone, the longer people have fun. I also enjoyed filling spots with neutrals who are not in my clan, give them a chance to zone/rank, but that is also something that has not been able to happen.
There is no way to satisfy or fix every problem. We can have group limits of 12 again and some bots will fill spots, we can have group limits of 6 and bots will fill spots there too. At this time though, the ripple effect of this group limit change is real players are being left out. The game is great and fun, we need to try to get as many active players engaged and keep them engaged. The news about some nerfs coming, which I may not be thrilled with, could be a great time to change group limit back to 10 for a little give & take in this adjustment process.
