I hope they reconsider. I remember when they recently made a POLL about co-op and other aspects of the game. People did favor co-op a lot in comparison to PvP. So I hope they focus more on the co-op aspects.
I remember that in this POLL, in general, people did show co-op matters. Unfortunately, when Larian showed the results to people on twitter they made a mistake by changing the name of one of the bars from "PVP" to "Co-op" (and this bar was big, showing people do not care too much about pvp), so a lot of peope who saw the poll thought players didn't matter about co-op, when in fact this bar was supposed to mean PVP.
The experience from personal quests only going to the player character/group that completes the quest is intended.
In the full release this will be changed. There is still personal XP for specific origin quests, but the XP differences that can develop are much smaller than in the alpha.
Raze, so the quests XP and monsters killing will be shared equally between people, but the specific origin quests wont?
