Can you guys change the way this achivm works? Being the first one who open a supply crate is VERY difficult… imagine having to do that 25 times.
You simply need to be one of the seven that opens, you do not need to open first. This said, the achievement is currently bugged and does not count in City of Threads Zone, only the other three spawn locations count.
You can also realm hop and obtain multiple credits to the achievement in one spawn as they always spawn same spot. You only need ten for the highest tier and best to do late at night or at server refresh as those have less people on to compete with. Do in Raids!
