Well said Gamekeeper.
If they indeed spent last 3 months on removing / tuning the effects, with all the optimizations and stuff that will happen over the next weeks/months - hell it might take them 3 times longer to bring back stuff to the way they it was before they started removing the undesired effects.
The only hope we have (scenario in which this will resolve soon), is if they have made a checkpoint / backup before removing epilepsy dangerous effects from the game, and that they can put them in easily. However, I am afraid that this is very unlikely.
"Reverse engineering" and bringing the effects to the desired (proper) look over a longer priod, is something that will probably happen more likely IMO.
These are all speculations on my part. Then again, I reserve the right to be surprised. As this game is continuously surprising us all.
