Best/Worst Changes in 5e compared to earlier editions

[Alucard89]

Technically the damage equivalent of Legendary Resistance is slapping on moar hit points.

Yes, but then your awesome CC spells have a chance to work. It's less about killing as fast as possible (then just have 3 Paladins and any boss is dead in 2 turns) and more about giving satisfaction to other classes.

Same as Bards without taking damage spells or dipping have problems in adventures with undeads or enemies again immune to fear, charm etc.

While damage starts and stays at top all the time.

I don't think it would hurt to let bard CC dragon and look as awesome as Paladin smiting it to hell.
