As BG said above, XP events ARE announced - with a weeks notice - whereas GE's etcetera are sprung on us with no warning. I've stated a desire that XP events are done the same way, with no notice, but that isn't going to happen.
Stop rushing for the "finish" line - and enjoy the scenery along the way - it's a more enjoyable game that way.
I dont believe these events are just a spring board to get to "The Finish Line". Enjoying the game is different for everyone, some don't mind being level 200, 500, 900. There is a preference for everything, this type of event makes it easier to get to that scenery most enjoyable to you. Think about it you can make up a few months progress in 1 weekend depending on how prepared or far you wish to go. A pvper eyeing a certain range, a gvger, even a titan hunter looking to access more titans i mean even an arena player has to level to get more setups. This allows people to pursue content a lot sooner then they would, makes the game more enjoyable for them and really will help retain them long term. Like i said there are so many positives to this event.
