Fact: After the update it has become very easy to deal with phantoms. You know, I no longer have to run as the suicide Nader to clear out the first stalking Phantom. (I kept smashing the ‘F’ key so that when I went down, the granade fell down as well. Thus even if the phantom managed to survive, he was on low HP for the next encounter.)
But anyhow, the idea of letting the phantom do something while invisible does sound like fun. You know, helping a teammate up, sneakingly planting the dynamite before the enemy’s eyes, and actually being an alternative for the usual springy proxy rush. You know this way phantom would have some objective based tangent beyond just the kill/death ratio.
After all; Fragger can disable the EV and Vasilli helps you to spot enemy team members through walls.
And I do feel that his cloak visibility should be brought back to what it was before. And I am not against rolling back the melee nerfs. (Well, the movement speed reduction on bigger melee weapons could be kept.)
Anyhow… just my two cents.
And on fun note… I love playing against a team of phantoms on the Bridge map, presuming that the objectives are guarded by at least two Auras and one Skyhammer: healing and ammo made killing invading phantoms almost effortless task before the patch.
