Thank you for sharing your opinion with us! Allow me to give a response with my opinion as well, if that's no problem with you!
In all honesty, since I am on Feral-heart ever since 2012(or 2013 I forgot but I am very old), I do miss the old maps along with general and other funny things we used to do in the old days. But now, don't get me wrong, ever since the bugs begun hitting the game and KovLKD left the game to the current Admins, everyone was begging for an update. When the update came (Howling, roars) we wanted more. I have no problem if the old maps get added but the current ones be kept (yes it might bring confusion to where the RPs will be gathered but I guess people can short this out) just like when South pole was dadded, they just added new maps and kept the old ones. But considering it might cause lag to the game they decided it was best to keep the old maps out since the variety of people were complaining. In all honesty, I do feel you and I understand you miss the old maps but we kind of asked for an update. When we first got Roar and Howl we adored it but then we wanted more and more, the they added south pole, lonely cave etc. etc. Which was a possitive but people kept asking for more and more updates until we got these maps. So I think it's our fault for never being satisfied. I think alot of people, however, left because the community because so sore, no offense of course I am a part of it to, I mean that it grew to have a feeling that people who will have unrealistic colors or something different than the 'used realistic standard' will be pushed away, judged and asked to change and it pushes people away. I am not sure if the old maps can or will ever return, depending on the variety of people and the agreement we can all come to, but we could think of an alternative way that would benefit most of players. Merging old and new maps MIGHT work but may cause great lag to the game.
Atleast think of the possitive side; The game is still playable with alot of nice people in it :DDD
Thanks for taking time to read this and sorry if your desire on the game won't be satisfied but I hope you still enjoy the game regardless!
