i kinda think you all missed how the game is currently.
If you created a healer in this game , you are at a huge disadvantage already.
You get XP relevant to the damage you inflicted on the Mob/Creature/NPC
whats a standard party healer/warrior/ranged/scout
the healer gets no XP
the scout gets minimal xp
the ranger gets some XP
and the warrior gets lots of XP
now im not going to say this is straight out bad.
this eliminates power leveling. (as it stands there is no level system here) - so if your a new player you cant just walk around with a big player and pick up PP
you can get loot while traveling with the big/old player. but no PP or very minimal for the little amount of damage you inflicted.
i was thinking about this a couple of days ago myself.
i was wondering if the dev team could use the (when you view someone else and it gives you a rough gauge of their combat strength to yours) to make a forumla similar to other games
to distribute the XP.
so if i was considered near impossible to defeat by another player , they would get like 2% of the PP/XP for being in the party.
where as if the other player was about the same strength as me the XP/PP was divided 50/50 - so if was the healer and my group member was the warrior , i would not be at a disadvantage for keeping him alive.
But aside from all that. how it currently stands you are better off gaining PP on your own , or standing there taking hits for you friend while they struggle to hurt the beast/NPC
I travel to unexplored places with friends in groups for safety reasons not to gain more Tria or PP
the group thingy is a usefull way to keep track of the people your looking after and to seperate the journeyers chat into another window

Also i would like this game to not include a mini map or an indicater of where your party is located.
the speech bubbles that show through walls is enough to indicate direction of sound , for when they are shouting at you

[which adds so much more realizim to the game]
