Ok you're now telling us more information which helps and changes things i.e. you fitted a new cable. 
This now narrows down the possibilities a little. A clutch is really a simple but ingenious device and there is little to go wrong. You're telling us it's difficult/impossible to change gears with the correct amount of free play at the lever...right? This is telling me there's not enough travel in the release mechanism and that isn't a great deal to start with.
The clutch basket being pitted isn't normally the cause of insufficient travel of the release mechanism it's possible but unlikely, what is more usual is semi seized or bent/broken/cracked release arm. The fact that the clutch will release albeit without free play suggest to me something is bent, broken or cracked, this happens when too much force is applied to the release mechanism. As I said earlier you need to release the cable, inspect the release arm for bends/cracks and then check it's operation it should be possible with a tube/pipe over the end to move it, although there is spring pressure it's operation should be smooth in both directions. If it's not there's a problem in the clutch it's self, probably warped plate or plates and or a damaged pressure plate, spring/s or bent bolt/s any of these will make the clutch heavy and reduce release movement.
