Well, not to get into an argument, but based on the tone of your post, with the multiple damns, it came across (to me) that you did not enjoy doing the research.
I've read your post a few times now, and I still can't "read into it" that it's a better system. That's the one problem with forums, it's so easy to misunderstand what someone is trying to say.
I doubt though it's taken you an hour to complete most of the research, there are a lot of research projects (from what I've seen in the thauminomicon). That would mean 1 minute or less to identify the aspects, move the runes around, read the research results (to unlock later research).
Time is a sensitive subject. For myself, time is quite valuable, and it seems that TC4 is going to take up a lot of my time on the research. I got quite frustrated with the slowness of TC3 (as you indicated) and this looks like it could be the same. Until I try it, it's all first impressions based on watching other people try out the mod.
I do like that there is no resource cost for the research. TC3 did hit you with a 3x cost to get it's items. First the research cost to get the aspects from materials, then the material cost to build the object, and again the material cost to get the needed aspects.
Just to be clear, based on first impressions, while the research system is more impressive, it appears to be more of a time investment and so turn people away from research again (and again) in new worlds.
Hopefully I'm proved wrong. I am looking forward to using the mod. Just the research system still seems the "weak" part of the mod.
Edit:
As you've replied as I was replying
I'm aware of the infusion crafting. I'm in two minds on that one. It's a nice system, but I'm not keen on having to babysit the crafting process to ensure that items remain on pedestals, replace destroyed items, etc.
Not so big a deal on items you might only need 1 one, but on some things that you might need a lot off, it would get frustrating
