TF2 Which weapon is unfair to deal with?

[sand.]

For me, it would be the Dead Ringer

 

[SL]

Same.

 

[Race]

I'd probably say the vaccinator...

 

[Redds]

Natasha. I just hate that movement speed. It feels like a crutch to kill scouts and soldiers. Honestly anything that moves.

 

[Gibus]

The huntsman. Too lucky for other people, but I never get the same luck when I use it.

 

[Green.]
