When: Every 30 seconds or so, in-game lag spikes causing the screen to freeze for 1-3 seconds and then fast-forward to catch up. AoE/boss effect indicators showing up too late for me to react on screen before the effect hits. This just started about a week or so ago. End-game content mostly unplayable.
