Yea it's pretty awful. I've played over 12 hours of WvW this past week and ended up with 8/10 on my WvW defense weekly, I really hope if nothing else they remove this as a weekly because its completely out of your control as a player. Between that obsidian sanctum, and the inability to skip or pick your dailies I switched to PvE only for now despite WvW being my primary game mode.
