My Elite

So some of you may still know me from 2 years ago, 

I might come back to alora. But was wondering what game mode I should start playing, since I de-ironed my almost maxed elite ironman around 2 years ago. 

I still remember having alot of fun, but quit playing back in the day due to lack of commitment and life hitting me hard. 

Is there any good stuff I missed out on? And what are the biggest things that changed since I was gone?
