To be honest, very similar as an elf spear/dagger. Just not done as often I think due to heartseekers are such a drawcard with hummingbird pendants.
Good int and dex both combine for a great combination with some legacies. Only real downfalls are that of HP. Which can be counterbalanced with gear really.
For playability purpose taking out the RP aspect, I would choose arial (Having had two spear/dagger arials) Though I do think D-Elf has more RP depth than the arials do.
