I had the perks, but was not using the gear. I would be disappointed if it was too easy to complete on hard. I would however appreciate it being possible when that is exactly the type of situation that my character is built and specialized for. I have yet to be able to beat an 11 or 12 node bypass with a 20 second timer. Similarly, those hacks are maddening with sluggish PC controls, especially when you have to complete two hacks within a time limit.
Havent played the PC version but have heard that it is harder to control. Might sound stupid but I didnt know it for a while, on the node hack you can go from far left to the far right allowing you to skip from side to side, that helps sometimes too. Also I think part of the problem is that you need to multitask, for instance I normally am looking at the other nodes while moving to the one I need, this allows me to be constantly moving and not waste any time.
Best part about it though is you can skip most of the minigames with EMP charges anyway so at least the devs realized that the games werent for everyone.
