I've got nothing against ranked dryads or chariots really but neither feels quite right.
Dryads fill a useful role in the army already, having access to relatively cheap disposable trouble shooters that can clear out chaff or hold up larger units is really useful, sure they could do that ranked up, but I just feel improving eternal guard or adding a cheap core elf unit would be a better fit for ranked infantry. Hopefully when the new book comes around we won't need ranked-up dryads.
Chariots can easily be explained in a wood elf army, but to me chariots are a status symbol used by more 'civilised' races. I just can't see wood elves bothering to make one, they don't make any other type of warmachine, and any self respecting highborn would surely much rather ride some fearsome forest beast anyway. Also, and more importantly imo, anything that brings them more into line with high and dark elves should be avoided.
But anyway, like I said, they're not game breakers for me, I would happily accept both in exchange for beastmasters
