I understand this is not guildwars, it is guildwars2 and that is fine. One thing that made things go smoother in guildwars was the ability to gain moral boosts. For those who do not know what that did a moral boost gave you more health and energy after you killed a boss. A person could have up to 10 moral boosts over their regular health and energy. Moral boost also could bring you back from having lower health. The lowest health and energy was when you were 60 death points. With moral boosts that can be raised back up. It could also be raised up with kills, but could not be raised past your normal hp and energy. Only time it would raise past normal was by killing a boss or bosses.
Now here is my suggestion and it should be world wide including dungeons. Since the dungeons now will not allow someone to rez at waypoints give the team if you are on one a moral boost for killing a boss which include named, champions, and veterans. That moral boost should always give one of two things either a resurect orb, or a repair kit. This can be directly from the boss killed included with other things maybe in one of those packs instead of the liquid karma.
Also killing normal foes after so many are killed the same thing should happen on the last one killed on that number the orb or repair kit should drop this can be only if armor is damaged say kill 50 foes to get it. This will be soul bound so to speak. That way if someone changes professions they will have to start over with it.
Just a couple ideas to look at thanks for reading
