D&D General D&D 6e ala Steampunkette: Structural thoughts

[Zardnaar]

That was the point of fighters back in the TSR days too. That and and having a ton of hit points, great AC, and usually the best saves on average

Yup.
. If you cut fighters back to one attack you have to have non scaling cantrips (or cut them), and reign in danage dealing spells by a lot.

Or you bloat it in other ways eg 2W, 3W etc which is kinda silly.

Moot point until you decide what to do with monster HP anyway.
