@ogunther Well... let's offer up some alternatives and discuss then... we've been very open in making some design changes based upon suggestions here.
There's always room for improvement... but the way that PvP system has retained players has been magnificent for the game. So I think "broken" is too strong a word. I can understand if it's not to someone's taste though... that's a matter of personal preference.
Regarding the current iteration of Guild Wars... I personally like the system... I look at it and see extra free stuff for everyone who participates... with top groups of participants earning LOTS of free stuff.
If your objection is that other players who work harder and coordinate better than your guild will out-earn you... that's a legitimate position to have. I don't think we can ever STOP that in a competitive game, but we can look to soften it.
If you can make top 10 in trophies, you can make top 10 in Guild Wars... at 10th slot, if all of your members buy 4 levels of guardians, they all profit 160 Gems + Cards + Gold for effectively doing what they did anyway. I can't really see the downside here
