Buffing 4 elements Monk was needed.
Potions as a Bonus Action is good. The potions are so weak it doesn't make sense to spend your Action drinking one. I'm not sure if a much lower amount of stronger potions would actually be better though. It seems silly a potion heals for 4 even at low levels.
Weapon Abilities are a good idea. Being able to Topple or Cleave once per rest is weird though considering how weak the effects are. They should be redesigned as free-to-use abilities that would add some oomph to standard attacks for tactical choices. E.g. Warhammer / Backbreaker: -2 Attack, enemy has to roll Str save or fall prone. And there should be less of them. Something simple like Blunt = Knockdown, Slashing = Cleave, Piercing = Cripple (debuff). I still don't have any idea what they do after a few years of playing. I just click on them randomly when I have nothing else to do.
Wizards learning all Cantrips was good but I think they removed the scrolls. They should let Wizards learn all Cantrips but having to prepare them like all other spells. They're cantrips. What kind of a Wizard doesn't know how to cast Light or Mage Hand? Then if you pick the "basics" you're starved for combat options or missing out on fun stuff like Minor Illusion.
