Honest maybe, correct…no. Your logic is quite faulty. " if it happens to a few people, it has to be on their end." Absolutely not true. By Blues own post there are several errors that effect a very small number of players that was on their side.
The reason for this is the insane variability of client and hardware configurations as they interact with their software. Some of the resultant error will be due to the user’s side, but some are definitely bad code on their side that only a few people will experience based on the difficulty of reproduction.
I would kindly suggest you refrain from such non-data driven statements that deny other’s realities when you lack the ability to judge the situation as it approached gaslighting although it is evident that is not your intent. (odd given the number of posts you’ve made).
Giving feedback is great, but really think things through so as to avoid making problems worse. Peace!
