Old Synth mechanic

Hello there, i just Watched all the old Content reveal Trailer for PoE because i wanted to know what happened in the past (I Started playing PoE in the Heist league), and when i got to the synth Trailer i was a bit blown away because i just LOVED the idea and i would wish for some re-implemintations of it like the map world building or something similar like that (maybe a extra warp point like for delve that you can find pieces in normal maps and you can bring them there to build a synth world or something) since synth atm. Is a bit how should i say, lost? I dont feel like its really present since even if we skill into the full synth tree we will only see map drops really rare and its only for the big unique maps not like Shaper/elder/Sirus/Maven and so on. I'am pretty sure a lot of other people would agree liking to see it in some way again in the game even if it means that normal/magic/rare synth items get a bit more rare because it could then be focused more on farming them in that "dimension/realm" like resonators and stuff in delve.

Thank you for reading this
