It doesn't sound too bad, to be honest.
I was worried that we'd get something along the lines of an enmity meter for the whole party (where you can see enmity of every party member) and therefor constant yelling from so called elitists that force you to stay below a XY% enmity threshold.
A four tier icon that only you can see is vague enough for me to feel some excitment while hitting stuff. ;)
