hmm ... more than a few exploits available.
Friends cantrip means you're Friends right?
CR 1s and then they gain one of the 3 classes.
CR 1s are < the CR 2s that Moon Druid 2 has been dominating with, so this is OK.
Basically way more race choices, and potential combos.
Warrior is preferable to Fighter at any number of levels.
Second Wind 1 level early, and Danger Sense > Str Save prof.
Battle Readiness > Barb 7.
Expert doesn't have Rogue's Sneak attack, but
Helpful is frontloaded Mastermind 3.
Jack makes it > at skills.
will get whining about > Rogues Sneak.
Evasion without sneak+, is only where it starts to fall behind.
Inspiring Help makes Lore 5s cry.
Capstone is quite tasty, make Wiz Div 2s cry.
Spellcaster again needs line iteming comparisons.
Personally I'll bet Warlock is weaker, but the others
aren't necessarily weaker at all.
The 6 10 and 14 if in regular classes, would get lots of whining.
( ... obligatory c.o. says damage is least valuable tactic, but still)
And probably easier play style for less experienced players.
