But when it comes to ranged units, it's hard to beat Darkshards. Shielded, good damage, Archer's arc of fire so they don't need direct LoS, and almost full AP? That's very powerful. Archers do have the range advantage, and Skaven skirmishers at better at kiting, but for cost Darkshards are amazing in both single player and multiplayer. à
Dark Elves in general are just an extremely good, well rounded faction. Good heroes? Check, Malekith is a monster, the Death Hag is also quite powerful. Good infantry? Probably the best, Corsairs, Witch Elves, Black Guards and Executioners are all very cost-effective and powerful. Good ranged? Yes as I stated. Good cavalry? Mostly, Cold Ones are good, Dark Riders can be helpful. Good monsters? War Hydra and Black Dragon say hi. Good artillery? The Bolt Thrower is pretty good in general. Good magic? They basically have the best Vortex, and Lore of Shadows is not to be underestimated either.
Every other faction has holes in their roster; HEs lack solid low and mid tier infantry as well as AP ranged, Lizards lack good skirmishers, Skaven lack good magic (apart from broken summons) and good AP infantry. So I think DEs are the best faction generally because you can build damn near anything with them, and close to their entire roster is good. But I also don't feel that they are broken or anything, in fact the balance at release is remarkably better than WH1's at release, there aren't that many broken OP or useless units.
