This ruins some builds and enables more.
First impression makes me realise that Life Cleric 1/Bard 6 for full plate aura of vitality at level 7 is now redundant. Life Cleric 5 does the same thing now. Because Paladin lost it's exclusive spells, and early access on those inherently stronger spells is available to clerics and druids.
Then the Warlock Necromancer comes in strong, with the ability to cast animate dead and also don full plate as an action.
The rogue has some sniper options now, Aim is great but it kind of takes away from Rangers.... although ranger got a bunch of nice stuff and are now more viable. My archery build just got stronger because everything got buffed.
Rogue/Fighter/Gloom stalker ranger - does a ton of burst in the surprise round, but now it can aim on subsequent rounds and has options like favoured foe and the ambush fighting style.
Speaking of fighting styles, you can use one fighting style to gain a maneuver, and then you can change which one you know whenever you take a long rest. Which opens up fun ideas, a fighter with at least two maneuvers who then gets into a combat lite social situation can swap out some combat ones for studious eye and silver tongue, and then get high deception, persuasion, investigation and insight checks.
