Who is whining? Everyone is stating their opinions or state of sadness regarding the removal, demeaning the entire community of your game by saying they are "whining" is rude as hell and 100% unproductive. Don't ask an opinion if you will only tear upon that opinion and enforce yours all while judging them whiners and lazy...
Here is my opinion. AS IS, this command removal is terrible, just simply absolutely terrible. Honestly I think it is extremely pointless and a huge waste of time that could spent on so many better things. The /list command was something Unique and special about PWO, as you rexrene are so bent about pointing out "no other mmo has this" well... YES! that is one of those things that makes PWO so different and so fun to play, it was something golden to have placed in a MMO, and now you take it away with the aim of making it more of an adventure...Make it more of an adventure by adding more things, not making everything more difficult and harder... When you go to another poke MMO like Pokemon DOD, one of the things you see players asking all the time is, where do I find this pokemon? how long does it take? etc. and NO ONE EVER ANSWERS, they simply say don't be f#$@@#% lazy go find it on the wiki, and that player is never seen in chat or game ever again, or that player will rant about it resulting in a kick from server. It was interesting when the crashes were frequent many people flooded to DOD and the one thing they all said, was how lame it was there was no /list command like in PWO...this command is what separates your game here, making it unique, original, and very enjoyable. In DOD I simply quit playing, the community is 100% unhelpful, the whole find the pokemon on the wiki is like a chore and really takes away from the joy of the game, and PWO had many more things i liked better such as /list command. This is only taking away and will only push away players old and new alike. Hunting here is already hard enough, this game requires way too much time to get what you are looking for in the first place, this only makes things so much harder, not making a better community. If your goal is to have a stronger community that is more involvement and communication, do things like weekend events, add guild functions in game, hide outs, hosting guild wars awarding said guild with bonuses, etc etc Add things to this game that give further functions and people will want to talk about it, don't take things away, from what I see all this has done is caused 75% of people to be sad and jump in to say they don't like it, kind of the wrong attention.
Now as for improving it... as we are now calling it "zebbys idea" I think you are on to something that is good. With the future additions of new maps, new pokemon, event maps, etc.. Having a /list command only showing Unkown - ?? ?? (pokemon - rarity) and leaving it to the player to unveil those pokemon upon finding and then using the command again to say Croagunk - Rare would be something that could be very interesting. I seriously doubt anything about this idea will further unite the community aside from having similar opinions against it. This new idea though, I am all for zebbys idea, as well for rarities, that is something that keeps someone hunting, knowing what general chance they have. People don't have the time of day to sit around hunting in the dark no idea what poke is where and what rarity it is.
