Okay so, at the moment I'm maining a Warrior. I had this situation when me and my Resto Druid partner were up against some Rogue and a Holy Pala, and we were stuck in there for 15 minutes, because each time I cc'd the Pala and tried to kill the rogue he would Vanish with 20k hp left. Realizing that would last forever, we decided to take it to a 1v1 brawl between me and the Rogue. He opened, I got him to 50% and he blinded me. I trinketed, stunned him, got him to 15% and he vanished. Then, he opened with a silence and immediately bursted me. The thing was, after that stun, the silence remained and I couldn't cast anything. For those of you who don't know, silence is making a player unable to cast MAGICAL abilities. I myself am a Warrior, therefore all of my abilities are PHYSICAL. I couldn't cast Rallying Cry, nor Shield Wall, so he got 280k off me in a matter of seconds.
Why am I unable to cast PHYSICAL abilities, while being silenced?
