I haven't been able to get my group to play Shadowrun in a good while, there are so many serious issues. I really hope the community gets a chance to fill out surveys, polls, questionnaires, partake in CGL run threads that actually get looked at, etc. I really hope they don't just all of a sudden drop 6E without giving us a chance to help shape it. Here are some things I seriously hate:
1. Priority System Char Gen: This is the reason people optimize so heavily, it really sucks to lose 50+ karma during character creation, it's unfathomably poorly designed and it needs to go.
2. The Matrix: Way too slow and complicated, very few groups enjoy it as is.
3. Poorly Written Rules: In Anarchy you can one-shot a car with a pistol. The conjuring rules don't exist, there is no target number and no consequence of failure. Drones rules are seriously lacking. Then 5E has too many issues to list, mostly too complicated to remember/be fun.
4. Shadow Talk: Please keep it out of rules books, you don't see this kind of thing in every D&D book, it's filler and I don't want it, just put a fluff section at the beginning or end of the book if needed.
5. Skill cap being 12(13). Simply way too high and not fun rolling absurd amounts of dice. When people buy tiny dice just to play that is a sign there is a problem.
6. Most of the Negative Qualities are horrible and unusable/not fun at all.
I could go on for quite some time but that's all I'll mention for now. Feel free to disagree but I know that there are many people with similar opinions so I don't think it's fair to say that everything is fine.
