Sorcerer trained skills

[KageNoRyu]

Iam currently in a discussion about the sorcer r trained skills pre and post recent updates.

In the pdf it seemingly stands that he is automatically trained in all bloodline skills Iam sure in rhe print d book i didnt see that nor is it on hero labs that way.

Now the question is: pre change how many skills did the sorcerer have trained at level 1?
(If really 5+4+int. why was it reduced)?

There was a major change in the most recent errata -- signature skills were completely eliminated. Instead of granting four signature skills, a sorcerer bloodline now grants training in two specific skills.

This change rendered moot the prior errata that eliminated the statement about sorcerers being trained in their bloodline signature skills (which was inconsistent with the way other classes were handled).
