yes, a guild war is supposed to be a war between guilds.
as i said, the current system promotes quite the opposite: leaving guilds. since only 10 players can earn the boss card, this system promotes having 10 players in different guilds.
the current system only promotes proper guild wars between the guilds that are very close to the top. for any other guild, the system promotes dividing guilds into subguilds with 10 players each.
the competition you have in mind, only applies to the guilds that are very close to the top.
also, consider the fact that the same guilds are on the top on every war. which further reduces the ammount of players that can earn the boss cards
people are leaving their guilds and making their own, or at the very least one guild is divided into 2 or 3 guilds.
also, from a post above i also see players are being booted from their guilds.
PM, you want guild wars to be proper guild wars. the fact that people are leaving their guilds and guilds are being divided during war week, it should tell you something is wrong
this is regarding individual rewards. guild rewards are even worse since only 3 guilds can earn them, and on every war they are earned by the same 3 guilds.
no other guild ever bothers going for it except the ones close to them.
since guild rewards are out of the question, we're left with individual rewards. and since individual rewards are also limited, it promotes guild division. which in turn promotes the opposite of proper guild wars
