FFX isn't a challenge with the use of Yojimbo. When I needed to get Anima I had to re visit Besaid, encountered Dark Valefor, and at the time I had terrible stats. Yuna went to over drive, I summoned Yojimbo and he Zanmatoe'd for the price of 1 gil. I thought I'd go after the other Dark Aeons, Dark Ifrit, Dark Shiva, Dark Ixion, and every time I summon Yojimbo with Yuna in Overdrive and pay him 1 gil, he Zanmatos for me. I'm getting bored now, so I refused to use Yojimbo and just beat Dark Ixion when you have to fight him again. Does anyone else think Yojimbo sort of ruins the whole challenging feel to the game when it's an easy solution to every fight?
