From next week, we will be adding Hyjal into our regular weekly 25 person raiding schedule. We don't want to add another day, so the plan is to drop HKM/Gruul at the same time and integrate TK and Magtheridon into a single raid. All the days/times will be the same, no change there. Here's the new schedule :

Friday - Hyjal (5pm-9pm server)
Saturday - SSC (12pm-4pm server)
Sunday - SSC (12pm-4pm server)
Monday - Mags/TK (5pm-8pm server)
