Speak for yourself. Shadow is a way BIGGER issue to me.
My 50 DPS is a shadow (alt) and I want to do HM EC one day with her.
I've done HM LI, SM EV and HM EC since being moved to the Super Server and no lag to report. Before when hitting the Fleet with over 200 on it I would hit serious lag, but since the move I have had none. On the The Harbinger and I am in Texas.
