I know I'm late to this thread. First, apologies for the problem having in the first place. We have since disabled DS Thresh, and we have a team working on a potential fix. We are testing it over the weekend in hopes of a hotfix very soon.
To give some behind the scene context- once we get these types of reports- we attempt to get as much information as possible to see how widespread the problem was. We worked with our data analytics team and saw that this issue was pretty wide spread and made the decision to disable DS Thresh. So, when we say we're working on it- it implies we are studying the problem, seeing how wide spread it is, what types of players and machines it's happening on, are there other factors (ie server problems, latency problems, etc.). Once we determined it was for sure DS Thresh and in what type of conditions- we were able to gain enough information to make the call to turn him off.
Totally agree- any feature, skin, champion etc..that causes such widespread disruption should immediately be turned off to protect the overall player experience.
Thanks for sharing your thoughts. Genuinely, appreciate it.
