Guild Wars 2

I was running HotW recently and I was firing off certain CC skills when I noticed that the CC duration seems to grow shorter with each application. Do bosses have diminished returns on CC duration or is it just me?

No they don’t unless they get stacks of a fury buff which most bosses don’t. However, bosses all have 2 buffs, one reduces CC and condition duration across the board(50% i think?). The second buff has 5 stacks and makes them immune to hard CC(can still cripple them), everytime you use a stun, fear, knockback, or daze the stack goes down by one until the buff falls off and then you can CC them and the stacks reset.
