Shadowknight vs Paladin

[Toxigen]

Solo: if not super twinked, SK due to fear kiting efficiency. You need a lot of stuff to make Paladin a solo powerhouse (narandi crown, fungi, deepwater BP, big CHA set, bags and bags of 10 dose Kilva's, etc). If a pull goes bad for paladin its root n scoot and hope you make it out. SK just FDs and its k.

Duo: about the same really, with 1 exception. Paladin actually duos very well with enchanter but its a different playstyle (you're the support).

Grouping: equal, you stand in camp and hold aggro...slight edge to paladin for sub-optimal groups I guess.

Raiding: paladin hands down because Soulfire can save raids and DS is a great buff.

I prefer paladin all the way. I had a blast leveling mine (but was mega twinked). If you love the SK aesthetic then do yo thang.
