I was just thinking, because game seems to favor creation of large PvP guilds, but also PvE zones are important, how it will be organized.
If it will be possible to join all members of smaller guild to larger one, but keep both guilds active.
For example when you are member of 30 ppl guild and you do PvE raiding with them mostly, but same time all of you are also member of PvP large guild to do PvP and have access to AH.
Will in such case be possible to have two chats active - one for PvP guild and one for PvE? I think it should (must) be done this way.
In GW2 you could be member of more then one guild, but you could "represent" one guild at a time only, it simply did not worked fine because while representing one you completely lost communication with the other guilds.
Also being member of large PvP guild makes sometimes trouble joining team with well known friends, instead you are joining with random ppl. Plus smaller guilds can have active voice communicator, while large guilds need to use many channels and it makes a lot of mess.
In my opinion multi guilding is good idea, but you need to be active in all of them all the time. You can have only one guild visible outside, but communication should be open same way as if you were active.
If it is possible then I could be memebr of:
1. PvP large scale guild - not much communication, only coordination of large scale battles
2. PvE raiding guild with friends, you could do both (PvP and PvE) with friends you know and with voice communicator, In PvP scenario you could read large scale goals, but tactical actions could be done in coordinated teams.
3. Some other smaller guilds like family or old firends guilds that usually do not play together, but like to chat sometimes.
