Active Camo yes ,should not be an ability, neither should armor lock though, like you said, it is pretty easy to counter and its only real use is against vehicles, especially ghosts, meaning the vehicle or course.
I actually like the jet-pack when it is used right, like to get onto another part of the map, that you could also get to by foot.
It does need fixing and I hope to see it back, but I admit I don't see a way to fix ti myself.
The Other Abilities actually improve gameplay without breaking it, in my opinion of course.
THIS NEXT PART IS MY OPINION ABOUT THE OTHER ARMOR ABILITIES, FEEL FREE TO SKIP TO THE BOTTOM AND IGNORE IT
------------------
Sprint - good simple and useful, and hard to be used to be cheap
Evade - Same as above, even harder to cheap with.
Drop Shield - IDK, I have seen it used to jump to areas you are not supposed to get to so I am iffy on that one.
Hologram is my favorite, I love tricking people with it. Bum Bait indeed.

THE OPINIONS ABOUT THE ARM. ABILITIES ENDS HERE
Anywho thank you for learnin' me, and I do see where you are coming from, I just created a thread complaining about people misusing things to break the game, albeit if a different way. Thank you
