There are a few other things that AE2 might learn from Refined Storage as well. For example, the ability to have an Import/Export bus filter, or just a Destruction Plane be able to filter. Maybe have a Filter Upgrade that works like an XU2 filter? Either way, extremely useful.
But if AE2 were to get rid of the meteors in favor of crafting plates, that would be a whole 'nother story. I get why it was done, the author wanted AE2 to be less early game than AE1 was. But I personally feel that it was an idea that was proven to be... less than ideal.
AE2 could also stand to incorporate the fluid storage from Extra Cells, which Refined Storage took care of in-house.
I guess we mostly agree, it's just a difference of opinion about which you want more: complexity or lack of meteors. You way in on the former, which I absolutely respect, I weigh in on the latter.
Yea, Refined Storage is kinda 'easy mode', but it does have some useful concepts that AE2 may wish to incorporate in its final design for 1.10.2.
