One of the main problems with hack objectives is that the other team is not required to have Operatives as well. On the Missle Launch map (shipyard?) the resistance can have all 8 of their guys go either soldier/medic/engineer and they are always buffed up. The security on the otherhad need at least 2 Operatives if they are to even be successful at hacking and therefore wont have as many classes to buff or medics to revive.
The engineers reverse hack tool is very fast. You can die at the objective respawn, and see the hacks progress go from 60% to 0 before you even get half way there. Considering how slow it takes to travel to objectives it might be worth considering making the engineers freeze considerably slower, the attackers should have a decent chance to stop them. At the moment you can be fighting near a hack and have an engineer slide in and start reversing, by the time you switch targets the hacks progress has already gone down quite abit.
