Well, i was a bit bored so i thought i'd add my 2 cents... or whatever. There's a fair number of things i'd like to see but not sure/worried about which one i want most or which ones can/cant/are already being done (partially cus this is a rather large topic). Anyway... wishlist:
Special Familiars: i know that i'd like one for one of my chars (a tiny yugoloth would be cool) but mostly i'd just like to see variety in this on level up/char creation.
Special Races: i believe the appropriate comment on this is

.
Expanded DM team: cant really say much on this except i'd liek the DM/Player ration high enough to perhaps have more personal plots for people. Also i've noticed DM activity rather low in afternoon GMT. At this point i should probably note, i'm available a lot of the time, so if anything is needed in the way of writing or whatever, i have some experience in the area.
Improved Spell/Feat Variety: as i'm sure you can tell, i like to be able to have lots of choices, makes players think more about what they want on their chars and forces more variety in play style.
Improved Class Variety: i know this has come up somewhere in this topic from my brief scan of the last page in the topic, but there's a few in particular i'd like to see. A decent warlock blaster PrC for instance or perhaps (though i'm sure this would involve far too much work) a fix for the warlock that allows them to take normal arcane PrCs as they are allowed in PnP.
Builders' Stuff: I'd also like to see a few things added to the builders' area of the forums, namely a list with hak order etc. Would love the ability to submit personal areas to the server, of course these would be built by the players/volunteers so as not to eat up the team's time.
I suppose that's it for now at least just one last thing to say to the whole staff on their work for us players

.
EDIT: Not sure what the word on this is, but there are quite a few things in kaedrin's custom content i'd like to see. Namely loads of the pnp fixes.
