Apex Legends fans know the struggle of finding an early Care Package to find absolute garbage. Respawn Entertainment has obviously seen the frustration and buffed the drop rates of legendary weapons only found in care packages.
As before weapons like the Kraber had a 7% drop rate in the first couple of zones, increasing only as the game carried on.
Based on the above information, every phase of the game has a 25% chance of dropping a legendary weapon. This may have to do with the fact that Kraber has been torn apart compared to previous seasons.
Respawn may be okay with players finding these ridiculous weapons because they aren't as broken as before. Comments on the Twitter thread were quick to share their experiences finding crate weapons much more frequently and this would explain why.
Respawn may be testing this system out and change it at a later date. They just recently fixed some Vantage bugs and will probably need to focus on a myriad of other problems like the hidden supply bin trap.
Expect these problems to take priority before they start messing with drop rates again.
