Hench why my vote goes out to a Marauder nerf as being one of the first nerfs in game ;p
Pretty sure this might be the case as well. This does not mean that BWs will not require tuning but in the last build in the CB Sorc's were slightly ahead of BWs in the damage department in T4. Marauders were extremely good with moderate healing due to piercing bite + widespread demolition tactics and AE knock-down. We will see
