I want to experiment with me as dm being the one to ask for a particular roll. We do a mixture but deep down believe it would be more fun if we said what we did and the dm calls for it. We may try when it my turn. My kids are green and would not even know what roll to call for.
That said we played yesterday with standard D&D. Regular dungeon. Some fomorian giants…some wraiths etc. and it was so fun.
I'm probably the one calling for the roll 80% of the time or more when I DM although I don't really keep track. I just don't see why it has to be that way 100% of the time. I've thought about doing more things where I roll for the players, but that would require the option to roll without a player seeing the result which is difficult since I don't use a DM screen.
