Huh, never thought about Midas before... That's an interesting one. Have to go for that some time. I still think Radiance is kind of an oddball due to the farming required to get it up and running, but hey.
As for desolator, I think it might be worth considering to build an Ass Cuirass instead. It's not that much more expensive, provides some armor and attack speed bonus (partly in the form of an aura, which allows you to blend slightly more into a role as a later-game support for your harder carry) which blends well with your ability to innately increase your own damage, and deals an armor debuff that affects everyone nearby and is only one point lower than that provided by Deso.
For hilarity: Aghanim and Refresher on Juggernaut (plus some mana/int boosters to pull off the combo).
Fun fact: Shadow blade can be activated while Juggernaut is spinning. It can also be clicked while doing omnislash, but will not activate until after Jugg is finished jumping.
EDIT: More fun; Although spinning with blade fury disables Juggernaut's main damage, targets that would normally receive cleave damage from battlefury will still receive the usual amount of damage. Criticals are factored in.
I'm done with dota for a while.
Had a really bad game that I just had to abandon it made me really upset.
What happened? Why did you have to abandon?
