Thinking about previous MMOs I've played for the past 25 years, I can see a potential issue with the party size being 8 players.
If content is based around 8 players, and to balance around each archetype being involved in each party. I have a feeling it might be tedious, and/or take a long time to fill all roles.
The idea behind an 8-person group is to allow us to really amplify party roles, and to create a need for each of the archetypes in every party.
Pros -
Diverse group dynamics
Difficulty of encounters
1 Tank, and 7 fillers?
Cons -
Time to fill may be longer than the actual content
Loot distribution can be thinned
1 Tank, and 7 fillers?
Meta builds / groups.
What's everyone's take on group size in AoC compared to how people play MMOs this day and age with Meta builds being so prevalent?
