1. So far we have no guild storage that I know of, and all players are self sustaining with their crafting. There is trade between players, but nothing organised guild wide. Your point on resources is therefore not applicable.
2. We are on a PvE server, not RP, so I doubt you will see much RPing going on.
3. There are many players who are getting into the PvP side of the game though. The PvP is still in its early development, and with the huge amount of soul combinations makes it difficult to perfectly balance. At this stage, there are certain classes that do seem to excel at PvP and this will be a work in progress to balance.
4. You can avoid Rifts a lot of the time, but eventually if players do this the invasions will overcome quest hubs and NPCs will be gone. So far I have found no hassle getting on with the game if I wish to avoid Rifts, there are always plenty of players defending the area from invasions. However, you will find Rifts are the high point of the day to day gaming, and the rewards/xp you get from them really do supplement the normal levelling.
