let’s put aside the question of why would they increase the rate of epic vault keys compared to the first vault weekend, if they were truly ‘dropping as intended’
In addition to the well-documented track record by the developer ref. ability to control its code and willingness to acknowledge & correct QA shortcomings, we now may be facing a scenario where a small, hand-picked segment of the playerbase (those currently in the beta programme) are given access to information that should arguably be equally accessible to all players (e.g. alleged increased rate of epic vault keys compared to the first vault weekend), even though customers in the Official Forums continuously asked for further clarifications on the observed inaccuracy of the ‘10%’ ratio of Epic Vault Keys.
Noteworthy potential favoritism, should the trend persist.
