imo Phantom is terribad and would need a whole new rework.
The idea of making his cloak a primary, especially signature ability is ill-advised because it feels like a bunch of incohesive stuff is being added to it in an attempt to make it good.
Removing cloaking from Phantom's identity would only serve to help the character develop a cohesive and effective role.
Phantom in general needs a serious refactoring. He just simply isn't versatile enough to justify a slot in any competitive matchup. Too much of his kit relies on close range and being the center of attention, or on enemies having poor communication and coverage, and he doesn't have the utility to back that up.
Totes on the bushwhacker buff though. I think I want to test it out soon.
Cloaks. Pubs hate them. Competitive laughs at them. Competitive cries with the saddening but anticipated disappointment when a cloaked character just can't perform compared to an explosive, combat-oriented monster known as Fragger, Thunder, Soldier, Demoman...
The list goes on.
So what's the big deal? Why do we have to have a cloaking character be built exclusively around going invisible?
Taking a look at these voice lines, Phantom's character being closely tied to his cloak is an understatement.
Phantom's primary problem in competitive play is that he is given a very incohesive, highly coupled role. His identity is reliant on his cloak in the extreme and this makes balancing his character difficult if not impossible.
Because of this Phantom gets utility that makes his cloak incohesive and a jumbled mess that is less of a cloak and more of a lawn sprinkler. Sitting in the arctic tundra, shooting human urine over a runway.
I think that Phantom needs to be refactored and cleaned up so that the abilities he has works together in a more useful way. Countering deployables is great and all, but I think that Phantom should not have one ability do two things that are counterproductive to each other and have that ability's effects be coupled to a certain style of play (which was Phantom's existing problem).
Decoupling Phantom from the style of play currently encouraged for him ("sneaky" moron with close range equipment) which was proven to simply not work is the best way to get Phantom off his ass and employed for once by serious interests. (Competitive.)
This is my main opinion on this matter and I might add more to it as I go.
Here's how I define a sniper class:
They have two sniper rifles for primaries (out of 3)
Aimee, Redeye, and Vassili are sniper classes, period. There are also no other sniper classes in the game.
Hey, Grandeur sucks now! Can we give it to Arty?
Make Aimee an assault with three charges of Jarate and Aura speed.
I blame Aimee for ruining sniper rifles. Especially the Grandeur.
