Yeah, Maxing out mark of the assassin is good if you are continuously a back line fighter in a group battle or attacking 1v1. I do crescent slash for the fast aoe farming of minions and jungle mobs to get alot of money. I also wait for people to engage and get my buddies to half so that they continue to get greedy and focus on my buddies. I shadow dance in and spam the maxed lvl, low cooldown C slash for aoe dmg (which = alot of healing on myself). I've blown up non tanks in a group battle. Doesn't work well if u dont have Last Whisper. (Learned that the hard way) :(

I like the build. Just played a game with it and went 16/0/7 before reaching my frozen mallet. The only thing different is I maxed out Mark of the Assassin first and i don't have any runes because I'd rather spend IP on characters, and I'm only level 25 so I don't have the masteries in the Def Build, and i went Ignite and Exhaust. But I liked the build.
