let me apologize in advance for all of the suggestions! i do think about how much work would be required if any of my suggestions were implemented, so again, forgiveth.
i'd like to see new gates opened up with new maps and monsters, maybe even some new bosses.
but in a new gate set up where you can have party sizes exceed 4. i guess sort of like a raid (i've never played wow), really, but on a much smaller scale. looking at 5-maybe 8 max. 8 seems like it would be very difficult to design for, so 6 seems like a realistic max.
as always, thoughts and opinions wanted.
Honestly four feels like a really good cap. If you start adding more players the impact of any one is going to be greatly diminished.
This isn't like WoW where players have distinct roles to play in combat. There is no real tank, there are no healers, CC and add management is more ad hoc than anything else.
It's basic hack and slash. When you add more than 4 people things get cluttered and it's easy to feel like you aren't contributing.
