Thinking about SR5, I decided I'd figure out a few things I'd like to see in it.

1) I'd like to see Technomancers following rules more closely to those of Mages, just for ease of play. Follow the same basic ruleset, but tailored to the Matrix, and we're good to go.

2) I'd like to see a more fleshed out section on Astral Space, and what we can do there.

3) I'd like for 'cosmetic' cyberware / bioware, to not have an Essence Cost. Seriously, save Essence Costs for things which are more invasive, and involve 'removing' or 'replacing' parts of the body. If I get cybertattoos, they should have zero impact on my Essence. Also, if you're born with genetic engineering, it shouldn't impact your Essence at all... after all, this IS your astral template. Why the hell would it impact your Magic or Resonance? (After all, you can make a full-blown clone Mage with 6 Essence out of the box in 4E).

4) I would like to see a little more detail on commlinks, what you can put in them and such. A focus on consumer society (apps and the like), and how these work together with the character.

5) I'd like to see the magical paths a bit more divergent, so they stand out a little more.
