Guild Wars 2

http://wiki.guildwars2.com/wiki/Control_effect

Per the wiki
“Control effects, also known as disables, are a set of effects that temporarily prevent actions or movement and disable all skills for the effect’s duration. All control effects will interrupt the target”

List of Control effects:
Daze.png Daze
Fear.png Fear
Float.png Float1
Knockback.png Knockback (Push)
Knockdown.png Knockdown
Launch.png Launch (Blowout)
Push.png Pull
Sink.png Sink1
Stun.png Stun
Petrified.png Petrified caused by Thief tango icon 20px.png Basilisk Venom
Elementalist tango icon 20px.png Ice block caused by Deep Freeze from Conjure Frost Bow.

so why does Fear not count as an interrupt in game?

I curious about this change as well
