i've used Classtimer for awhile now and it does what i need. but i don't know if mine is bugged or i just never noticed before, but it's showing the target debuffs i specified but not just mine. it's showing other players diseases, shocks etc.
Some people have told me that their Classtimer doesn't do this, but mine does too. What I did was that I changed (for my DK, I changed to MagicRunes and let that show my diseases on the target) classtimer out with PowerAuras, and set an aura for those abilites. It's really easily done and quick too.
