I mean "a third of their time" still comes out to around 300 hours of combat streamed. I'm not disagreeing that 5e is better for shows but I think talking about a lack of 1 hour, gridded combats being the reason when the biggest actual play show has a good amount of those things seems inaccurate.
And there you go.According to Running Stats, the average time spent on combat is a little less than an hour. The longest combat was 2 hours 18 minutes in campaign 2. Longest in campaign 1 was an even 2 hours.
So no, I haven't seen 3-4 hour combats in Critical Role.
Sure, there is combat...but it is not 4E style combat.
