Seriously the most obnoxious sounds in two games that put the fear of mesmers in your heart.
In GW1 it was skill canceling in general but most of us know it from being interrupted by those pesky mobs of Wind Riders. Who will be brave enough to attempt to cast the first skill in this fight?
In GW2 it is that troll noise from a mesmer using Power Lock to interrupt you. Thankfully Wind Riders in GW2 are a little less evil.
Anet buff me :-(
Make me good at game!
