A couple ideas here that I have had for a while!:
1. Pet birds. I was thinking that maybe those useless birds could do something meaningfull, like send in - game messageges to people far away, acting like a PM, but not a PM... it still makes them useless in a way, but oh well. Birds could also deliver gralats safely from point A to point B, and maybe pick up stuck gralats that might be on the map. This would give them some sort of point. You could add/remove owners just like bomy pets, and buy them at auctions or just from other people.
2. Personal Horses. It wasn't that long ago that Asuka and I both won these, but never got them. They were set to our accounts so only we could ride and maybe call them... what ever happened to that? Well those could be auctioned/sold from players too.
3. Pet Ducks. Just to show off your wealth.
Well, Serena, Corpse and I all thought it would be a dandy treat to get something cool for getting 1000 hours... maybe the first 3-5 people to get there could get one of these lovely things I brought up. Post comments about it please -- if you still can...
