To be honest, 5E has been one long stream of disappointments.
I wouldn't go that far, personally, and I've thoroughly enjoyed the Season 5 and 6 Missions. But, and this is a big one for me, the lack of Errata after several official statements to the effect of "It's coming" is inexcusable, and not helped by the continued push to produce more paid content. I've stopped buying books other than Missions until Errata that fixes the core rule books issues is released, personally.
The thing is though that Missions has had to go out of its way to patch things which normally aren't working in the regular rules, which is why it's generally enjoyable in 5th edition. Kudos to the Missions group for working hard to fix what's broken so that it can be used in Missions games, but they shouldn't have had to do so to this extent. Even then, there's only so much the Missions team has been able to do.
Missions games were the only Shadowrun games I could get in this area, and I was happy with that, but due to the state of the rules there hasn't been a Missions game in this area since November of 2014. Last month was the annual gaming convention held locally, which was in its third year, and it's the first year it didn't have at least one Shadowrun Missions game listed. No one, including the GMs, want the hassle anymore.
The deal with the errata has gone beyond ridiculous now; it was a problem in SR4, SR4A, and now 5th. First we were told that it takes time because they have to discuss errata changes and then test them out to see if the changes are balanced. Over three years of testing for some of the errata for the original books? Really? Then we were told that they didn't have the time/resources/whatever to put the errata in a nice pdf layout yet. Come on now, most of us, if not all by this point, would be happy for a plain text wordpad/notepad document with errata.
At this point, the only way I can see to fix 5E is to just simply let it die and have 6E come out, with something closer to 4E's rules.
I for one really hope they don't do this; 5th works well enough, more so than 4th in my opinion. Sure, there are internal inconsistencies particular, in my opinion, around the Matrix, but nothing that can't be fixed.
At the very core of 5th, I like what they were trying to do. I like the priority tables being available again, although I wish it was a bit closer to the last version of it. I also like the alternate creation methods being available, especially the life modules (although if you're going to have life modules or something similar, that really need to come out in the second book at the latest so that all archetypes can benefit in the following rules expansion books. I like the idea of limits. I liked the thought that RCCs and especially cyberdecks were going to have value again, until rules came out that largely erased that thought.
Scrapping the whole thing and starting over is a no-starter for me; I also have zero faith that Catalyst is the company to do this, as evidenced by the shameless copy-paste from prior editions that are already prolific in 5th.
I would change the second part of that to "I also have zero faith that Catalyst's Shadowrun employees is the team to do this..." As has been talked about a lot in these forums, Catalyst's Battletech team doesn't seem to have these issues. When problems arise with their rules, they work with the players to get errata turned out. Just to clarify though: When I spoke of the Shadowrun team I am
not talking about the freelancers (those people have gone above and beyond in trying to help out, in my opinion), but rather the editors and line developer (and whomever else might be be involved above the Freelancer level).
I believe I mentioned once before that I was thinking of abandoning Shadowrun, except for the novels and enhanced fiction; over the last few weeks I've pretty much committed to that idea. I may pick up the Tir book (pdf only, so that it'll be updated when it eventually does get errata), and I will get the Tarot deck (if for no other reason than the incredible art), but other than the novels and enhanced fiction I'm pretty much giving up on Shadowrun finally. I'll get my cyberpunk fix via novels, video games, and other systems.
