Let me first state, I've been playing for 3 weeks now early and have had no lag at all with a lvl 48 character.

The last 24 hours I've experienced what other people are this "lag" out of no where.
My guess is it's something you've done again.

I'll note I haven't had any issues prior to the last 24-48 hours.

ISP: iPrimus
