Best way to get caught back up?

Hi, im returning after not playing for around 6 years and wondering if theres a reasonable resource for catching back up with all the new systems, as trying to learn it all at once is a bit overwhelming and I dont feel like resetting my progress back to level 1 from 100. Any help would be greatly appreciated, thank you.

 

I hate to sound unhelpful but since the skills are so vastly different now I really think the BEST way would be to reset.

if you really dont want to reset you could look up some more recent builds and try a few out. reseting skills is pretty cheap.
