Don't Play the Sheet...

Skerpies at Coins and Scrolls once said this about the Glog (a game with features per level like 5E).

In play, class features and abilities don't actually come up as often as you'd think.

I've read a lot of comparisons to OSR play that talk about not playing the sheet and this sounded about right to me. Now I've GM'd a few sessions of 5E and found my old AD&D gang doesn't look at the sheets during play (except to find where to click their attack/damage/init which on Roll20 are done by clicking the sheet). 

I had to remind my players about the Second Wind and Action Surge features (after the battle when they almost lost two PCs). This makes me appreciate Lamentations and other Basic variants that just give you a better to hit, or better skills or whatever, and leave the rest up to the player as it seems the problem will get worse as they get additional features each level. Also the features feel a bit video-gamey.
