What about deso? Thinking about it, the minus armor seems good, would be nice if its effect is applied by blade fury and omnislash.
It can work but it's very glass cannon, use with caution.
I'm guessing if you open with blade fury you should be able to clear most of what could be problematic unless its furion's treants.
I wouldn't count on that, especially in team fights. Can't afford to be spinning on creeps, your team/you will die while you're busy not using that ultimate. Better to use it sooner rather than later in most cases.
