I still believe that there is no way to turn off the toggles is a bug.
When using Void Destruction skill; fire - burst on and around target, dark - Jump on target, however is there is no stance it will use power attack on single enemy, also all the skills graphics are different which is nice to see what is happening, also that the skills in quick links do not change showing it is selected as a dark/fire sometimes.
It just makes sense for the stances to be able to turn off, such ads having a wind weapon and using it rather than overwriting with dark/fire.
I rather have the option to stop the toggles, also when using the dark/fire; having the skills that use them, icon changes like it was before, however seems to have an error now and can stance with it showing no effect icons on the quick skill links.
