So if the sudden removal of a slew of powers/weaknesses from Shifters was purposeful enough to warrant not approving the errata to reinstate them, why isn't there some sort of reasoning to go with it?
One of the biggest reasons people get upset by these sorts of changes is because there isn't any information being passed along to the consumer (players and fans of the game). This game has a history, the line developer (Jason Hardy) knows that, he's been involved in Shadowrun for a long time, right?
So if something fundamental is changing, like how Shifters function as a species, why can't we get some sort of answer? Since Run Faster was released this has been a topic of debate, hotly contested as to whether the removal was purposeful or accidental. Along comes the errata team, a welcome reprieve as the books haven't seen in nearly 3 years. They propose that the powers should all be there, which itself implies the absence as accidental.
Now it gets blocked, throwing that existence into question again. Shifters are in an existential limbo; do they exist as they have in editions past? Has their biology changed somehow in the years since their release in 4th edition? Why do we have this sudden change, and why can't the errata add it back.
Failing to approve the Provisional errata has only brought up more questions.
