Made a weakaura for myself mainly for the tooltip on mouseover which isn't supported by Grid2.
Dynamic group shows debuffs that your healer class can dispell in top right corner (growing left) of raid frames with colored glow depending on its type and stack counter on outter bottom.
You may adjust some settings to your liking such as position, icon size or adding timers.
Maybe you find use for it. If you have any improvements or suggestions then feel free to leave a comment =).
