After the new knight of fate came out I was looking for more classes with Durable. I found the Gunner specialization from the Ace book, and was confused. The left side of the tree to me doesn't fit with what expect for a ship gunner. 2 ranks of Durable and 2 ranks of enduring, these can quickly turn them in to tanks but I don't understand what gunner would have them.
Does anyone have any insight in to these strange talents for the specialization?
