Sorcadin leveling question, 5/5 or 6/4?

[Nifft]

I thought one of the main selling points of a sorcadin was more slots to smite with.

Level 10 Paladin gets 4/3/2 slots; this character gets 4/3/3/1, plus whatever can be created from Sorcery Points.

Haste is a great spell, but it stacks with Extra Attack -- having haste doesn't make Extra Attack somehow worthless. Running Twin Haste on yourself and an ally at level 11 with Aura of Protection so you get to keep it up all combat is pretty great.
