As most of you probably know, when you switch trinkets that have a USE function there is always a set 30 second cooldown.
Although this may not be the most amazing or interesting exploit, it's a good one, because it works every time.
Simply find somewhere to zone in (instance, battlemasters place, raid, etc), and click the trinket you want to equip right as you are zoning in. You will find that after you zoned in, the trinkets' cooldown will be over, even though it has only been 1 or 2 seconds.
