ok i was helping a friend, i noticed my cooldowns was lasting longer so saw my haste reduction was lower than normal figured ok my gear is damaged.. so i used a repair kit.. my haste CD reduction didn't change... so i was realy confused.. i stood there talking and didn't do anything still had my character window open and saw my haste CD reduction go back up then go back down without anything on my changings...
i've been watching over past 30 mins and it has done this several times the majority of the time it stays at the lowered damaged rate of reduction but every now and then bounces back up to normal sometimes instantly dropping back down sometimes taking a few seconds to drop back down.
