Something I'd like to see investigated is the option to swap roles IF a player leaves the group.

I.E you get into Wanders palace HM, tank goes "BYYYYEEEE!" and your left queeing for another 20 minutes waiting for a tank to join in progress etc.

I would like to see it looked at the option of Having the players swap. I.E tank is under geared but has a very good BRD, so a dps swaps roles with Tank ( cos they have better gear as tank) for example. I can see some potential problems with this so it would need investigating first, something of a Token system possible that allows you to make the swap. Maybe you can only hold a set few token at a time and they cost Allied Seals/ Tomes/GC's to buy etc, Something to discourage people from abusing the system.
