I noticed lots of people feels unfair about how new players are given 4 character slots while old players only get 2.
Assuming ArenaNet's decision regarding character slot is final, I have an idea concerning this. It may be a good idea...or it may not; that is totally depends on how guildwars' community thinks about this idea.
Old players who owns both core and faction will given very special item, armour or skill. More like prestigous item/armour/skill for old players to make up for 2 lost character slots. To make things really unique, this prestigous unknown will be only availiable to one of your character.
Let's say prestigous armour for example. Upon log on screen, you will be ask to select one character; and that character will be given prestigous armour. Since it will be only asked once, it would be ideal to choose your main character.
Older players would feel unique, and that would be ArenaNet's way of saying thanks for staying with GuildWars.
