Took that dragon down last time I played, awesome fight
Rogues are awesome, I love switching to Sera from time to time. Glad I rolled a mage though, I like the extra dimension it adds to your role in the Inquisition.
As for the guide, if you're happy to read up on all the lore you find lying around, or ask all the backstory questions, it does fill in a lot of gaps. But I'm still glad I understood some basics from that guide such as Lyrium, Dwarves' role in the world, Mage circles/templars etc.
