Hmm if you talk about hacking in-game then i am not for it and yea like people says it spoils the game.. imagine a lvl1 wearing lvl99 equipments.. it really sucks and does not make it any more fun that it is set out to be.
Hacking on the actual work is very real and anytime there are real time threats around so being equipped with the skill gives you an advantage over those without as you are more prepared for it
