Derwoodly, there has been a lot of thinking on this. And in reality it will be one group, and later with sub groups, what this means is the overall leader will be able to sub divide his party up. You could have say 10 groups, each with a nuker, healer, thief and fighters?or there will be groups of healers, nukers, heavy infantry, light infantry and scouts? it will be up to the leader to choose how, and up to the user to see what info they want?if they want the status if subgroup B then they get subgroup B and all their vitals.
Also we have in the plans for group heals to not be centered on the caster but around the target?so healing at range will be possible at higher levels.
At least that is what we have on paper :-)
The big issue is group and subgroup designation.
On the, loot issue, that will be worked out, we will have loot that is only good for guilds, temporary loot?that you might as well use ASAP, money that goes to everyone involved?and other stuff. But the dragon dropping one thing is bad.
The better idea is the dragon drops 500 things and it is like a pi?ata of good stuff, but only one or two great things.
Also a list of everyone in the group and what they looted keeps people honest to a degree.
Since you can?t lie about not getting something, when everyone saw the text saying you did take it.
