You gave it the old college try, but I think it's time to recognize that the lighting changes you made to 5e just aren't working. Between disadvantage on attack rolls being a HUGE penalty and the frankly buggy way lighting is applied by the engine - for example the exact same enemy can be dimly lit to one PC and brightly lit to another character - the system is just tedious and I think unintentionally frustrating. It is also cascading into race balance changes etc., that just don't make sense and take you as devs farther away from your bread and butter which is providing a 5e game experience. I am not really looking for a direct response from the devs on the boards, but do want to spur internal talks among them about how they are going to get lighting back to something that works.
Typos happen. More so on the phone.
