The idea that Matrix Actions require Matrix connection is asinine.
SR5 p. 237 Matrix Actions
Matrix actions are only available in the Matrix.
Thank you for proving my point for me:
The idea that you cannot take notes on your commlink (Edit File) without a Matrix connection is very hard to swallow, and would be a prime example of why everyone should avoid 5e like a plague.
Combine that with paying customers are
still waiting for a comprehensive errata for the Core Rule Book (coming up on five years after release, with no finish line in sight) - that isn't a slam on the errata team, they are volunteering their time after all, and still have to have changes approved by some "secret" committee - and 5e should be avoided like a plague.
And I happen to like the basic rules system for 5e over 4th. Granted, that is because I cut my teeth on 2nd / 3rd, and 5e is much closer to 3rd than 4th. That doesn't take away from the fact 5e just isn't worth any money at this point.
Almost everything that involves technology in 5e needs to be reviewed, and much of that rewritten. If Sixth Edition isn't slated before the end of the year (with a comprehensive errata available within a year of release - or at least very strong evidence of it being continuously worked on) everyone should just go with 4e, or take the world into their system of choice.
