I loved that fight, and the aftermath even more! XD

And I don't think it was hard at all - 4 abilities (equivalent to Conjurer's Sastasha-level kit + Lucid Dreaming) don't take more than the 15 seconds required to skim the tooltips to master. It's not even close to the level of complexity you're expected to figure out in the Samurai introduction quest. If anything, the Sadu fight was the hard part. The masochist that I am, I did it on Machinist and failed 2 times. Once because my cooldowns weren't up for the dps-check phase and the second because I stopped paying attention for just a moment and found out that the telegraphs actually hurt!

In the Y'shtola fight, I ignored Hien's whining because he's 1: terrible at this game for leaving his healer to tank an enemy, and 2: terrible at this game for thinking that splitting damage was a sound tactical decision. Now I know why Doman Resistance was so useless before WoL showed up.
I did the correct thing and focused down the monk while kiting Magnai with Aero. Monk went down pretty fast, I only needed to heal Hien during the scripted phase, and then he was free to help me finish off Magnai.

Of course, no amount of damage he took during that fight even compares to the savage smackdown Y'shtola laid upon Little Sun afterwards... owwieeee... in front of Sadu, too!
