How to fix the dungeons in GW2
Point 1 and 2 kind of offset each other. If you are WP serving you will have high repair costs. A coordinated group has the reward of not dying, thus negating repair costs, and can finish the dungeon faster.
This seems like a great idea. Players would be punished less harshly for learning how to play, and more harshly for dying in a serious dungeon run. I think it would be a little too harsh to force players to start the dungeon completely over. Maybe there could be checkpoints. Anet already has a system that allows players to restart instances without waypoints in TPK, they use in in personal stories. It would be great if Anet added that to dungeons.
Number 1 gets you number 2, and if you actually coordinate and avoid number 1 and 2, you end up avoiding number 3. Even if you couldn’t meat rush, you’d still throw yourself at the boss until you beat it, the way it is now you’re punished for zerging bosses with high repair costs and eventually coming out with less than what you went in with.
