So I just picked up a box of Wood Elf Glade Guard at my
FLGS. Always liked the models, and I figure it's only a matter of time until
GW gives them an
AOS "re-release" with half the models for twice the price.

Now I'm going to use them to convert up an Exodite army using the Craftworld Eldar rules.I tend to like a balance between fluff and cheese. I want to collect models I like, that are thematic, but I don't want to get stomped every time I play. I haven't considered doing anything Eldar related in years, so my knowledge is a little rusty. I have a couple of questions.
Which is better as a core unit to build the army around, Dire Avengers or Rangers? I'm going to convert the Glade Guard into one or the other. Rangers seem like a very fluffy choice, but from a rules standpoint, I'm leaning towards
DA. They seem like better all rounders, and I can take the infamous Wave Serpents as transports. I'm thinking of getting some non-
GW dragon models, adding some Eldar bits, and running them as Wave Serpents.
Are Howling Banshees viable at all now? I know they were crap last codex, which is a shame, since they're so dang cool.
Which is generally a better Warlord, an Autarch or a Farseer? I guess it probably depends on the situation, but any advice would be helpful. Right now I'm leaning towards taking a Farseer and some Warlocks and going Psyker-heavy.
Any other advice for a Craftworld army?
