The real reason the population is declining is...

[Glam]

People stopped to play because of all cheating.......

wrong Q in begining...a few people did some good pp on them
Some people (wiz) and other used spell not classic to lvl faster than anyone else...
since its alot of experienced people who run server It should have been ZERO of this spells, quests, buggs in the game at start up

I know alot of people who is back and play blue but they all wont to have classic back but red server isnt even a options because of this big misstakes at start up....

But we all wish you gl on red server who will be another fail server just like TZVZ.....so just go blue and play it as it is since that server will stay 250+ all the time
