Since ive gotten a couple auras one being ae other being group Ive noticed something. Since the auras recast on zone in, every time I zone in I must wait for the aura to spam before I can do anything(normally 1 or 2 seconds), as if its waiting for the server to sync or something. Sometimes, if I zone into a zone full of people ie vale or forest, the aura does not go off at all and my ping doubles every 30 sec or so until I finally quit out or disconnect around 8000 ping or so. This occurs on both ae and group auras but group aura doesnt happen nearly as often maybe 1 out of 30 zones.
With ae aura I can actually tell when its due to cast because the game sorta pauses its actions as if a zone crash or Im about to LD then the aura spams and Im good again. This normally happens in zones with tons of mobs as if its trying to cast the aura on mobs as well.
I do not know if others have experienced this but I do feel that it is an unnecessary burden on the server and client to have the ae auras spam on zone in or even auto spam. If there would be a way to make the auras castable via item obtained or something I feel alot lag/delay related complaints might be remedied. Its kinda the same if you remember the old raids where everyone started using mgb the game just kinda freaked out at all that had to be calculated at that moment and with more and more people getting auras its like mgbs casting every time someone dies/zones in/or its timer is up.
Just my observations like I said dunno if anyone else has experienced it but I can only imagine what it will be like in the future.
