Ive noticed that some mobs (also possible with enemy faction/duels ?) sometimes cast stuff that has a grey castbar, as opposed to those with colour. Ive also noticed that one can not Skull Bash (simplest feral druid interrupt ability) the grey casts.
So about that, any guide that can tell me about these two “categories” of casts ? Google hasnt helped me with this.
Maybe some lines in reply can tell me all there is to know ?
Depends what UI your using, I myself have not used the default UI for years so colourwise I maybe wrong but there are 2 kinds of casts ‘interruptible’ ones and ‘non-interruptible’, just going of a very vague memory of the default cast bars the non-interruptible casts were a greyish blue , while the cast you could interrupt were coloured.
Some UI’s colour the casts different by what school they are from , like Magic or Physical too.
