I disagree that gritty rest would solve the solution. At low levels, the classes tend to be balanced sufficiently. Starting about 7th level, casters have enough spells and their spells are sufficiently versatile, they outshine martials, especially fighters.Yes, this is pretty typical. This is how we play and I suspect how most people play these days. And gritty rests fix most of the issues for this type of pacing. I literally don't understand why people refuse to use it; using it is hella easier than redesigning the entire game from ground up around the assumption of fewer combat encounters between rests. The biggest mistake WotC did was to not make the gritty rests the default, as it better match the pacing of a typical game and a lot of people refuse to touch optional rules.
Gritty rest may mean that at higher levels, casters have to manage their spells more. This may give martials more of an opportunity to shine. But at low levels, it tends to have the opposite problem of making spellcasters feel underpowered.
