heh, maybe
but really, getting extra 1st level spells and maybe even a cantrip at 3rd level is too little too late for most spell.
they are good at 1st and 2nd level and fall of the cliff after.
frontloading is a problem, but on the other hand without it, characters are boring to play, I mean even now, everything under 5th level is snorefest unless you are a new player, characters simply do not have enough things to do.
our last fight, the rogue did same thing 5 rounds in a row, Aim+Elven accuracy with longbow.
why? because rogue, does not have really anything else to do, unless you are AT, but those spell slots will run out fast.
battlemaster? 5th level, well, you have superiority dice for 2 rounds, after that? d20 "auto-attack" like a bad champion.
