Admiral: Huh? Is this something you can only use while the ghost ship is floating? I don't get this one at all.
Tuskarr: TUp, that's how this effect could be readded.
PotM: Nah, we already have enough backstabs, that's kind of boring and doesn't suit her Ult's theme very well Imo.
Drow Ranger: Null, I find it average.
CM: That would be quite awesome, makes her less dependent on BKB or Blink Dagger to use ult, two items she can hardly get in any game anyway. TUp.
Puck: Null, this could ruin some of your allies' spells, grants your enemies control that you might not want.
KotL: Interesting idea.
Ogre Magi: TUp ^^
Axe: TUp, I like the general idea
Doom: Disabling the bonuses as well is a bit too oped Imo.
LoA: Would be cool, but insanely strong.
Magnataur: I dislike it, has too little to do with the Ult.
NA: A second manaburn is not really needed Imo.
Faceless Void: Nope, this makes it more like just another stun.
Bane Elemental: Interesting idea
Death Prophet: I love this idea, it's pretty cool, TUp
Lich: Would be funny, Idk yet.
Eredar: I like it, cool idea, TUp
