Yesterday was the time for few hours of low level static grouping: only our rogue couldn't join us this time. The four of us took the WSG first because it was the daily BG. As we are using the ingame voice chat due to a)convenience and b) being lazy, I was a bit surprised that the group chat settings worked inside the battle party and it seems that they override the BG party settings. Which means that our petty troupe chatted the battles away, either disturbing others or not: no one commented on our chatting in any form or function.
The other thing was our run in Ragefire Chasm (we had to take set dungeon, as the LFD complained about one of us "not meeting the dungeon requirements" in random): the voice chat doesn't work there at all it seems. At least it doesn't work when we have a substitute to fill the group up. Which in fact complies with the information Blizzard is giving about the LFD: the communication and trade between different realms is restricted.
However, the thing which was disturbing was something I dismissed the last time. As we came out of the dungeon, we couldn't get out of the LFD until we left the group completely. So we had to assemble our party anew after the dungeon. This doesn't make any sense: we join the system in a party, and after doing the dungeon we have to disassemble and form the party again to go to another dungeon.
This is the feature I hope Blizz could tweak out. It should be possible to run several dungeons with the same party, I my honest opinion, so that you could group with even the same random dungeon group for several dungeons in a row. Someone else has written about the same, too, but I forget who it was.
So the question is, is this must to break even pre-formed group before going for a new random dungeon a feature or a fault in the system?
