Which units would you replace in the Dark Elf faction?

I, for example, actually think that for a decisive battle, hunters are more suitable than assassins. Even if you're playing as assassins, it's much more beneficial to control them manually, and the stats of hunters are simply amazing! Besides, they attack once – without retaliation.

It would be interesting to introduce new units, like some kind of spiders. The question is – what would they replace? This is a very difficult question (maybe replace the riders? Or dragons?).
