I and a whole lot of other people think the time limit on invisibility is way to long and should be downed a bit or should be completely removed
they nerfed invisibility so much already. the scrambler does hardly anything and isnt confusing in the slightest. the only way to not be seen is to basically not move at all, you still show up quite clearly on the radar if you so much as blink. and its not all that hard to see you sitting in a corner. its fine as is.
i am peronally not a fan of the invis or jetpack, they both give to much of an advantge to the player using them. that being said there is slayer pro which has no armor abilities. but to answer the question i think they should get rid of or nerf invis and jetpack
