well dude i for one am glad its not your decision
(1) well if you cant go through mssions as an upgrade master or force enhancer then there is seriousley something wrong with the game as what if nobody wants to mission with you - then you are pretty much screwed as you cant solo a mission (example - you walk into an "easy" mission area and get insta killed)
(2) the game is about class diversity and i know hacker is overpowered and that is why im glad to see a leveling of the playing field with cr2. But where do all you kung fu addicts get off saying that they should delete the tree altogether except for doctor in effect you are saying to anybody who wants to be a hacker that you can go do some other tree unlees you want to be bored out of your mind rezzing and healing me because your tree is nerfed
(3)now imaging this scenario - my finger hovering over the delete button of the operative tree.
