this would cover most effects like
sorc weapon buff
dk weapon buff
dk armor buff
skills like grim focus
etc
this gets rid of the lingering effects while still allowing you to use the skills so if you use volitile armor you would still get the spike spray but the back horns wont be there.. or if you use sorc mage daggers you would still get floating daggers but the purpley effect wont be there...
now you no longer have to be see through stam sorc to do that great aoe storm damage/armor buff and can go about being actually normal instead.
its a practical necessity..
