In all honesty unless you have greater than 40k power, soloing Yagura difficult will be VERY hard and time-consuming. I'm lvl 75 with almost 30k power, but none of the setups on youtube worked, nor did my own. But, i managed to get the SA difficult done on my first try in a duo-attempt. So my advice is, forget doing solo unless you're very high power, and just do it in a team; you can literally auto it like a TI.
