Which means I have a fraction of a second to hit my keybind. It became trivial when I had memorised his skill rotation, but as I was learning it, boy did I fail numerous times… (and I'm used to interrupting, I did it for years in many other MMO's, with an average-to-good reaction time, and never in another game do I see a cast bar still filling up after I interrupted it).
The global cooldown which is twice longer than most casts adds up on the difficulty with the lag making twitch interrupting impossible and the interrupter is forced to have only one skill (the stun) on action bars. Pointing an example what these discussed issues effect.
