you wont have any fun if first thread on forum you will see on release day is about superoptimal setup one and only possible best
The point of the rework is to make it impossible to build THE ONLY BEST setup.
Of course there will be some generic strategies which usually work the best, but you can still do things different from reactor to reactor.
As well I will go with the common popularity-balance: Every component used by many people will be nerfed, every rare-used thing will be buffed.
