Unfortunately, the corrupted souls make it more difficult there. Fighting a crimson dragon is hard enough but the souls tend to mean you need alot more to take them down. On Origin alot of the time there are not enough to do that. 5 of us took down one in Trinsic because we only had to worry about anything but the crimson. However when you have to worry about the dragon and being attacked by 1 to 10 corrupted souls it can be frustrating.
