Hacks are made to have fun on warrock, mainly if your shit, theres Features that make you look good like chams and no recoil..
Superjump is fun coz you can stand on roofs and shoot and just, in genaral, a really fun hack.
Then it comes to stuff like Invisable and OPK...
They suck, there boring, Why do hackerrs do it?
maybe new hackers, in there 1st week of hacking they see a OPK hack :O :O :O
But pro hackers using opk is just bs, its boring, ruins game, even the hacker gets bored.. you get benned almost instantly
so thats my take on it
Conclusion
Any hacks that take 0% skill are for complete newbs at hacking
