Might start Aeldari - need some advice

[TheDreadfulSagittary]

Greetings!

I'm pretty new here on these parts of the universe, as I'm mostly an imperial collector/player, but was always intrigued by the "eldar" (still uncomfortable with the extra a...). I loved the bright colours and the specialized units. 

As 11th edition seems to be on the corner, and I haven't played since... 8th???... I'm considering to start a small new army for the new edition. Although I love Space Marines (especially the Blood Angels and the Space Wolves of 40k), but I have a huge pile of Heresy Marines, and I want to do something completely new. Also something exciting as a hobby and painting project! So Aeldari would be up for the challenge.

 

I know, that it is early, and nobody knows how the army will be played in the new edition, but what would you recommend getting? Things, with which I couldn't miss. What characters or units should be fine?

 

Thanks for the advices!

 

P.S. Somehow I managed to get a Striking Scorpion units   I know... but these models called for me since forever, and I had the chance to get them for a great price. 
There are not many options for them, but how would you build the exarch?
