As I am sure you are aware OP, SAMs have this ability that rings every so softly before unleashing a devastating blow. I like to hear it. I like to hear it a lot. There's another one. Their biggest bang for the buck kenki spender. It's makes an awesome sound too! And when I hear it, it lets me know that the SAM is aware of incoming damage. There's also this other one. It's friggin brutal. So fast that if you blink, you'll miss it but causes tons of damage and the mob's blood sounds like it's dripping all over the floor. The more I hear these going off, the more likely the SAM will get my comm.

I guess to sum that up quickly, the more I know a DPS job due to playing it myself extensively, the more likely another player using the same job will get my comm since it is much easier for me to recognize what they are doing.
