To answer your question i have used and do use my recommendation in 3/3.5. I havent in 5th because im still a relative n00b in 5th and have yet to dm it. But also i think 5th as it currently is might require too much restricturing to use my rest scaling recommendation. Maybe not though.A lot of these are house rules or rulings.
5e is clearly and explicitly planned for just that.
I'd love to know how many of you use these at your tables?
I am a Grognard of almost 40 years and have run nearly all RPGs RAR, with house rules that I don't even think about but just do as seems to suit the campaign.
So how many of these posters do these as house rules, especially the 5.01 to 5.10 versions?
How many have taken the SRD and created their own table variant?
