Dump Ability scores. Just use the bonus number.
Ability scores: since everyone is just so special, it should go from 0-5 because negatives are no longer trendy. Chart referencing is just archaic at this point.
Get rid of darkvision. Wth is the point if EVERYONE can see always anyways?
Dump skills and just use saves. Have specializations if you want.
Dump all spells above 5th from the phb. Wth do we have character levels..and spell 'levels' that have nothing in common. Call em A,B,c, etc for all I care.
Dump all the variant spellcasters. Jeez how many do we we need? Maybe add some more less/no magic-crutch classes back in.
Dump the video game feel that we have everpresent nowadays.
Hair, eyes skin whatever wastes space on character sheets and especially on VTT character sheets. They dont matter and no longer belong in the game. Age as a number? Heh. Good one. Yea we TOTALLY use that..not.
Passive perception. Holy heck if I have to listen to another smug-ling' belch about how he 'won d&d' Im gonna hurl.
Money. Ooooh, who doesnt love that worthless part of the game?
