The DDO LFM are nearly perfect. I think that every MMO should just copy how DDO did it. It's that good. I think it was key to the success of DDO's forced grouping. However, it is not perfect and there are a few changes I would like to see being done.
The only changes I would make are:
- Add a playstyle category when creating groups (zerg, exploration, sneaking, etc.)
- Add a roleplay option (checking yes would change the color of the LFM, for example)
- Add a permadeath option (checking yes would change the color of the LFM, for example)
- The ability to select (None) for in the quest category so we don't have to say Not doing the quest displayed
- Add wilderness explorer area to the list (Cerulean Hills, Ataraxia's Haven, etc.)
The first two can be added in the comment section, but by making of those a supported feature it would prevent counter-nature grouping (players wanting to go slow playing with zergers, non-RP and RP playing together, etc.) and allow such playstyles to develop.
As to why add the last two, the reason is quite obvious, I think.
