PoE2 party,guild,community interaction details

Hello
Can we get some information about group playing in PoE2.
At this point im struggling to find any information about it and im wondering to what dagree it will be solo game and what duo/party/guild players can get out from new version.

So i would really appriciate if anyone from the staff could reply with some answers for the following questions/topics or simply cover them in one of interviews, also if anyone plans to make interview with Jonathan please consider using below list of questions:

1. Will loot be split or each player gets his own
2. Will number of players affect loot drop chance
3. How exactly will atlas map exploration work will that use party leader map ?
- if so then will other players in party get something explored in their atlas or just rewards for party leader map completion ?
- if so how reward is going to be distributed (if at all)
4. Can all content before endgame be played in party ? (it was mentioned that campaign can be done in party)
5. How will guild and personal hideouts work for party/guild members ?
6. Will mobs/boss scale with player count (in party) ?
- what if different level players will do the content i.e lvl 60 with lvl 90 in such case will mobs be scaled for the players ?
7. How will PVP work in PoE2, will that be in EA, can You provide more details ?

Any answers would be much appriciated
Thanks
