SAM being top DPS isn't a bad thing. It is a selfish DPS job (which is healthy) and it needs to be worthy of its slot, especially due to the investment that's not there when you spread your damage around and thus suffer less from 1 person under performing. But then you remove the contributed DPS and see the raw numbers and SAM ends up scaring people by being so high. It just needs healthy competition. BLM is that job. Another selfish DPS. Magic SAM if you will. The issue is there is no competition there.
