Mostly because RL got in the way, in more ways the one. I am hoping I can do some new ones in the future but it will probably be still be a few months sorry :(
... the constant content they keep issueing costs money too. I agree with you the content in F&F was weak, 1hr of content like you said but its already improving and previous updates did keep me busy for a week or two as well. Though you're right that all of it lacked an element of challenge. So In closing not disagreeing with the core of what you said just think you're being a little bit too hard. But lets hope your intention gets through a nice hard expansion would be nice !
In most cases there is context if you want it. The dialog NPCs speak between different events in the same chain, talking to the npcs directly, even investigating the area seeing whats happening will nearly always provide the context of the event chain itself. Nearly every event happens for a reason and NPCs will tell you those reason if you talk to them.
No clue, could be browser or even flash itself, I would try updating flash or even test it out on a different browser see if that helps!
yes as well as, blow up bridges, setup siege points, take over whole zones, blockade roads, take over bridges, tunnel into forts, steal supplies and summon champion mobs.
