as unholy, keeping your diseases up is fundamental to your DPS. however, i first apply them, but then i start tunnelvisioning and generally forget to reapply them in time. i primarily run heroics, so for trash (that dies before the diseases run out) it does not matter, but for most bosses, i tend to lose a lot of DPS.
is there anything that can help me keep an eye on my disease uptime?
