yeah youtube has like no info about Tanlorin aside from that one build video you mentioned, just 'antiwoke' culture war stuff looking for clicks, the initial announcement of the companions also had some complainers on their forums, I'm way more hyped about Tanlorin as a new companion for questing, skipped out on a few companions before, the purple gear is expensive, they take a while to level, and I got used to hanging out with Mirri for questing and Isobel as a tank for dungeons and world bosses
