I also had issues with ''insta casts'' never had that before, it only happened three times during the siege for about 5 minutes every time. I couldn't use charge/miasmas or I mean, I could cleary hit the target I was aiming for, yet they didn't go off. I even shouted out on Team Speak during the siege, I have never experienced that before, not in any siege or at any point in pvp. I have a very good computer and an amazingly good internet connection, this is 100% server and game related and its ... not a common thing obviously but stil its very frustrating to be ''crippled'' like that in a siege.
