First up Disguising is a really usefull ability and so is hack turrets and comms hack (although it does take quite a while.) Cortex bomb is just so orgismic. I'v gotten revenge on many people with it. but the other skills seem pathetic.
Sticky grenades can easily be seen on the floor and easily shot, take WAY too long to explode, and are removable by the enemy teamates which is ridiculously easy to do, for damage that can't even incapacitate an unbuffed light. Caltrops is a mixed bag while it does give you a lot of XP when thrown onto chokepoints the damage is so meagre and the slowdown effect is marginally good depending on circumstance. The control turret imho it's so bad it's not worth even considering, first off you have to put the control device on the turret which takes a fairly large amouny of time, secondly you have to hole up somewhere and hide to use it, which isn't very beneficial to the team as it's much better to have a turret AND an operative behind enemy lines (Not to mention that you need to actually aim it which reduces the turrets effectiveness.)
With homing beacon i find that by the time the homing beacon has activated they are already dead and that's in the rare occurence when i am ironsighting (I usually hipfire.)
I have firewall, yet i have never come across it and so cannot gauge i'ts effectiveness, seems good though.
So anyone else agree with me? Or am i just not using them right? My 2 cents.
