You can go "blind" yet you should know lineage has no focus on questline like wow. Also, ingame beginners tutorial is very basic and doesnt tell you anything besides how to move and attack. I mean - no shopping, buff, craft, skill, or leveling tutorials avalible in game. This chronicles.. ehm, l2 Classics were meant for experienced players, mostly. But this is almost what Lineage was at the beginning, so its nothing impossible to understand, really.
I think there's plenty l2 Classic tutorials at the web, but my advise is to find a friend, party or clan to ask for advice and play with. Its a much more great and fun experience to see and learn by yourself, than just reading others guides.
