Guild Wars 2

Generally in the siege events you get the first half of the bar really quickly, but then the initial enemies are all dead and you spend 4-5 times that standing around waiting for enemies to SLOWLY spawn in so you can SLOWLY deplete the bar the rest of the way. Either the spawn rate needs to be higher, or the bar needs to deplete faster so the first part of the event is the whole event. As it is, the events are far too slow and have far too much dead time.

This is the running theme with almost all events in the game where you have to protect an area from incoming mobs. Lots of standing around bored while mobs trickle in 2 at a time. These kinds of events need to be shortened significantly and have the mobs spawn much faster (but still scaled properly for the number of player in the event).

Yea the defend events do take a very long time. Immersion wise I think this is perfect! It captures the essence of being taken by surprise by an army intent on murdering everyone there. But gameplay-wise I feel they do tend to drag on a bit. I would be fine with upgrading more enemies to elites/champions and having the bar deplete 25-33% quicker.
